BRENDA is a comprehensive database of enzymes maintained by the Institute of Biochemistry at the University of Cologne. Scientists collect and evaluate enzyme function data from primary literature sources. The site has recently been updated with new enzymes and an entirely new search engine. Various searches can be performed, including enzyme name, organism, or EC number. Links to literature...

Scientists Huan-Xiang Zhou, Stanislaw Wlodek, and Andrew McCammon created this animation showing "the 'breathing' motions of the gorge or channel that leads from the region outside the enzyme Acetylcholinesterase (AChE), to the active site." The enzyme AChE controls the communication among nerve and muscle cells. This animation demonstrates, for the first time, the role of molecular dynamics in...

This website features the Enzyme Structures Database, created by researchers Roman Laskowski and Andrew Wallace of the University College London. The database "contains the known enzyme structures that have been deposited in the Brookhaven Protein Data Bank (the PDB)." As of March 2003 the Brookhaven Protein Data Bank contained 10208 PDB-enzyme entries "involving 9873 separate PDB files - some...
