A global "map of the protein structure universe." The Berkeley Structural Genomics Center has developed a method to visualize the vast universe of protein structures in which proteins of similar structure are located close together and those of different structures far away in the space. This map, constructed using about 500 of the most common protein folds, reveals a highly non-uniform distribution, and shows segregation between four elongated regions corresponding to four different protein classes (shown in four different colors). Such a representation reveals a high-level of organization of the protein structure universe.

This ribbon drawing of a protein hand drawn and colored by researcher Jane Richardson in 1981 helped originate the ribbon representation of proteins that is now ubiquitous in molecular graphics. The drawing shows the 3-dimensional structure of the protein triose phosphate isomerase. The green arrows represent the barrel of eight beta strands in this structure and the brown spirals show the protein's eight alpha helices. A black and white version of this drawing originally illustrated a <a href=http://kinemage.biochem.duke.edu/teaching/anatax target="_blank">review article</a> in <i>Advances in Protein Chemistry</i>, volume 34, titled "Anatomy and Taxonomy of Protein Structures." The illustration was selected as Picture of The Day on the English Wikipedia for November 19, 2009. Other important and beautiful images of protein structures by Jane Richardson are available in her <a href=http://commons.wikimedia.org/wiki/User:Dcrjsr/gallery_of_protein_structure target="_blank">Wikimedia gallery</a>.

Opioid receptors on the surfaces of brain cells are involved in pleasure, pain, addiction, depression, psychosis, and other conditions. The receptors bind to both innate opioids and drugs ranging from hospital anesthetics to opium. Researchers at The Scripps Research Institute, supported by the NIGMS Protein Structure Initiative, determined the first three-dimensional structure of a human opioid receptor, a kappa-opioid receptor. In this illustration, the submicroscopic receptor structure is shown while bound to an agonist (or activator). The structure is superimposed on a poppy flower, the source of opium. From a Scripps Research Institute <a href=http://www.scripps.edu/news/press/20120321stevens.html target="_blank">news release</a>.

A study published in March 2012 used cryo-electron microscopy to determine the structure of the DNA replication origin recognition complex (ORC), a semi-circular, protein complex (yellow) that recognizes and binds DNA to start the replication process. The ORC appears to wrap around and bend approximately 70 base pairs of double stranded DNA (red and blue). Also shown is the protein Cdc6 (green), which is also involved in the initiation of DNA replication. The video shows the structure from different angles. From a Brookhaven National Laboratory <a href=http://www.bnl.gov/bnlweb/pubaf/pr/PR_display.asp?prID=1391&template=Today target="_blank">news release</a>, "Study Reveals How Protein Machinery Binds and Wraps DNA to Start Replication."

Proteins are made of amino acids hooked end-to-end like beads on a necklace. To become active, proteins must twist and fold into their final, or "native," conformation." A protein's final shape enables it to accomplish its function. Featured in <a href=http://publications.nigms.nih.gov/structlife/ target="_blank"><i>The Structures of Life</i></a>.

A study published in March 2012 used cryo-electron microscopy to determine the structure of the DNA replication origin recognition complex (ORC), a semi-circular, protein complex (yellow) that recognizes and binds DNA to start the replication process. The ORC appears to wrap around and bend approximately 70 base pairs of double stranded DNA (red and blue). Also shown is the protein Cdc6 (green), which is also involved in the initiation of DNA replication. Related to video <a href=http://images.nigms.nih.gov/index.cfm?event=viewDetail&imageID=3307><i>3307</i></a> that shows the structure from different angles.

Cryo-electron microscopy (cryo-EM) has the power to capture details of proteins and other small biological structures at the molecular level. This image shows proteins in the capsid, or outer cover, of bacteriophage P22, a virus that infects the Salmonella bacteria. Each color shows the structure and position of an individual protein in the capsid. Thousands of cryo-EM scans capture the structure and shape of all the individual proteins in the capsid and their position relative to other proteins. A computer model combines these scans into the 3-dimension image shown here. Related to image <a href="/Pages/DetailPage.aspx?imageID2=5875">5875</a>.

Solution NMR structure of protein target WR41 (left) from <i>C. elegans</i>. Noting the unanticipated structural similarity to the ubiquitin protein (Ub) found in all eukaryotic cells, researchers discovered that WR41 is a Ub-like modifier, ubiquitin-fold modifier 1 (Ufm1), on a newly uncovered ubiquitin-like pathway. Subsequently, the PSI group also determined the three-dimensional structure of protein target HR41 (right) from humans, the E2 ligase for Ufm1, using both NMR and X-ray crystallography.

Dengue virus is a mosquito-borne illness that infects millions of people in the tropics and subtropics each year. Like many viruses, dengue is enclosed by a protective membrane. The proteins that span this membrane play an important role in the life cycle of the virus. Scientists used cryo-EM to determine the structure of a dengue virus at a 3.5-angstrom resolution to reveal how the membrane proteins undergo major structural changes as the virus matures and infects a host. The image shows a side view of the structure of a protein composed of two smaller proteins, called E and M. Each E and M contributes two molecules to the overall protein structure (called a heterotetramer), which is important for assembling and holding together the viral membrane, i.e., the shell that surrounds the genetic material of the dengue virus. The dengue protein's structure has revealed some portions in the protein that might be good targets for developing medications that could be used to combat dengue virus infections. To learn more about cryo-EM, see the blog post <a href="https://biobeat.nigms.nih.gov/2016/02/cryo-electron-microscopy-reveals-molecules-in-ever-greater-detail/">Cryo-Electron Microscopy Reveals Molecules in Ever Greater Detail.</a> For a video of the entire virus rotating, see <a href="https://imagesadminprod.nigms.nih.gov/index.cfm?event=viewDetail&imageID=3748"> video 3748</a>, and for a still image of the virus, see <a href="https://imagesadminprod.nigms.nih.gov/index.cfm?event=viewDetail&imageID=3756">image 3756</a>.

This image shows a computer-generated, three-dimensional map of the rotavirus structure. This virus infects humans and other animals and causes severe diarrhea in infants and young children. By the age of five, almost every child in the world has been infected with this virus at least once. Scientists have found a vaccine against rotavirus, so in the United States there are very few fatalities, but in developing countries and in places where the vaccine is unavailable, this virus is responsible for more than 450,000 deaths each year.<Br><Br> The rotavirus comprises three layers: the outer, middle and inner layers. On infection, the outer layer is removed, leaving behind a "double-layered particle." Researchers have studied the structure of this double-layered particle with a transmission electron microscope. Many images of the virus at a magnification of ~50,000x were acquired, and computational analysis was used to combine the individual particle images into a three-dimensional reconstruction. <Br><Br>The image was rendered by Melody Campbell (PhD student at TSRI). Work that led to the 3D map was published in Campbell et al. Movies of ice-embedded particles enhance resolution in electron cryo-microscopy. Structure. 2012;20(11):1823-8. PMCID: PMC3510009. <Br><Br>This image was part of the Life: Magnified collection, which was displayed in the Gateway Gallery at Washington Dulles International Airport June 3, 2014, to January 21, 2015.

Scientists recently discovered the full molecular structure of telomerase, an enzyme important to aging and cancer. Within each cell, telomerase maintains the telomeres, or end pieces, of a chromosome, preserving genetic data and extending the life of the cell. In their study, a team from UCLA and UC Berkeley found the subunit p50, shown in red, to be a keystone in the enzyme's structure and function. Featured in the May 16, 2013 issue of <em><a href="http://publications.nigms.nih.gov/biobeat/#4">Biomedical Beat</a></em>.

Like a strand of white pearls, DNA wraps around an assembly of special proteins called histones (colored) to form the nucleosome, a structure responsible for regulating genes and condensing DNA strands to fit into the cell's nucleus. Researchers once thought that nucleosomes regulated gene activity through their histone tails (dotted lines), but a 2010 study revealed that the structures' core also plays a role. The finding sheds light on how gene expression is regulated and how abnormal gene regulation can lead to cancer.

Salk researchers captured the structure of a protein complex called an intasome (center) that lets viruses similar to HIV establish permanent infection in their hosts. The intasome hijacks host genomic material, DNA (white) and histones (beige), and irreversibly inserts viral DNA (blue).” The image was created by Jamie Simon and Dmitry Lyumkis. Work that led to the 3D map was published in: Ballandras-Colas A, Brown M, Cook NJ, Dewdney TG, Demeler B, Cherepanov P, Lyumkis D, & Engelman AN. (2016). Cryo-EM reveals a novel octameric integrase structure for ?-retroviral intasome function. Nature, 530(7590), 358—361

Cilia (cilium in singular) are complex molecular machines found on many of our cells. One component of cilia is the doublet microtubule, a major part of cilia’s skeletons that give them support and shape. This animated video illustrates the structure of doublet microtubules, which contain 451 protein chains that were mapped using cryo-electron microscopy.

Ribosomes are complex machines made up of more than 50 proteins and three or four strands of genetic material called ribosomal RNA (rRNA). The busy cellular machines make proteins, which are critical to almost every structure and function in the cell. To do so, they read following protein-building instructions, which come as strands of messenger RNA. Ribosomes are found in all forms of cellular life—people, plants, animals, even bacteria. This illustration of a bacterial ribosome was produced using detailed information about the position of every atom in the complex. Several antibiotic medicines work by disrupting bacterial ribosomes but leaving human ribosomes alone. Scientists are carefully comparing human and bacterial ribosomes to spot differences between the two. Structures that are present only in the bacterial version could serve as targets for new antibiotic medications.

Superresolution microscopy work on ER in the peripheral areas of the cell showing details of the structure and arrangement in a complex web of tubes <br></br> The endoplasmic reticulum (ER) is a continuous membrane that extends like a net from the envelope of the nucleus outward to the cell membrane. The ER plays several roles within the cell, such as in protein and lipid synthesis and transport of materials between organelles. The ER has a flexible structure to allow it to accomplish these tasks by changing shape as conditions in the cell change. Shown here an image created by superresolution microscopy of the ER in the peripheral areas of the cell showing details of the structure and the arrangements in a complex web of tubes. Related to images <a href="https://imagesadminprod.nigms.nih.gov/Pages/DetailPage.aspx?imageID=3779">5856</a> and <a href="https://imagesadminprod.nigms.nih.gov/Pages/DetailPage.aspx?imageID=3784">5857</a>.
