	What is a Protein? Proteins play countless roles throughout the biological world, from catalyzing chemical reactions to building the structures of all living things. Despite this wide range of functions all proteins are made out of the same twenty amino acids, but combined in different ways. The way these twenty amino acids are arranged dictates the folding of the protein into its primary, secondary, tertiary, and quaternary structure. Since protein function is based on the ability to recognize and bind to specific molecules, having the correct shape is critical for proteins to do their jobs correctly. Learn more about the relationship between protein structure and function in this video.
	How Enzymes Work
	Aconitase Aconitase converts citrate into isocitrate as part of the citric acid cycle.
	Calcium Pump The calcium pump moves ions across cell membranes allowing the synchronized contraction of muscle cells.

	Fighting Coronavirus with Soap Always use soap when you wash your hands! Soap molecules break up the outer envelope of viruses such as coronavirus, stopping infection.
	Penicillin and Antibiotic Resistance Since its discovery in 1928, penicillin and penicillin-related antibiotics helped save countless lives from bacterial infections. However, in the face of overuse and misuse of antibiotics, bacteria evolved resistance mechanisms that allow them to proliferate even in the presence of the newest antibiotics.
	Ebola Virus Proteins Tour the molecular anatomy of the Ebola virus with the RCSB PDB. Understanding of the shape and structure of the proteins that make up Ebola is a key component in the fight against the virus. Learn more at Molecule of the Month.
	A Molecular View of HIV Therapy After HIV enters a T-cell, three enzymes play essential roles in the life cycle of the virus. Reverse transcriptase copies the viral RNA genome and makes a DNA copy. Integrase inserts this viral DNA into the cell’s DNA. In the last steps of the viral life cycle, HIV protease cuts HIV proteins into their functional parts. Current antiretroviral drugs target these three enzymes, hindering the virus reproduction. However, enzymes can mutate and become drug resistant, making it vital to use a combination of different drugs that target multiple enzymes. This animation was created using many PDB entries for Reverse Transcriptase (3hvt, 3dlk, 3v6d, 3v4i, 3klg, 3v81), Integrase (3os1, 3os0, 3oya), Protease (3pj6, 1kj4, 1hxb, 2az9, 2azc), HIV Polyprotein (1l6n), Capsid Protein (2m8l), and Matrix Protein (1tam).

	Photoactive Yellow Protein and XFEL/SFX Structures of photoactive yellow protein were determined by serial femtosecond crystallography after illumination, capturing the isomerization of the chromophore after it absorbs light. Structures included in this movie include: 5hd3 (ground state), 5hdc (100-400 femtoseconds after illumination), 5hdd (800-1200 femtoseconds), 5hds (3 picoseconds), 4b9o (100 picoseconds), 5hd5 (200 nanoseconds) and 1ts0 (1 millisecond).
