Original – An enzyme ( TEV protease) bound to a substrate (black) contains a catalytic triad of residues (red). The triad consists of an acidic residue ( Acid), histidine ( Base) and the nucleophile ( Nuc). In the case on TEV protease, the acid is aspartate and the nucleophile is cysteine. ( PDB: 1lvm​)
Reason
This is a professional-quality scientific illustration of a protein, highlighting the key structural features underlying a very common catalytic mechanism for enzymes. The chemistry of the catalytic triad is commonly taught in undergraduate biochemistry courses, giving a high-quality illustration high encyclopedic value. (This nomination is a follow-up to the conversation in this recent delisting nomination for a dated- and generic-looking protein illustration. This newly nominated image would give us a high-quality protein example in a modern style.) Opabinia regalis ( talk) 21:45, 26 December 2015 (UTC) reply
