(Modeling proteins) (Chymotrypsin Mechanism: Step 1, Step 2, Step 3, Step 4, Step 5, Step 6)

Transition state between Steps 2 and 4 of Chymotrypsin Mechanism

  (PDB file) (ARC file)



In this reaction, water adds across the peptide bond between Trp252
and Thr253 and across the ester bond between Thr252 and Ser195.

This is obviously a nonsense reaction - it would have to be a multi-
step process - but it illustrates the level of complexity of reaction
that can be modeled.
