activating agent,active form, optimum pH of chymotrypsin

i may be wrong and misunderstand the author because i am not a native english speaker myself, however i believe he/she confused P and S. where the P site makes up the positions in the peptide to be hydrolysed and the S site the position in the active side of the protease interacting with the peptide to be cleave.

this can be looked up

Mechanism[edit]

The illustrated mechanism is wrong. The asp 102 does not deprotonate his 57. The hydrogen at that position in histidine isn't acidic to begin with. Asp 102 merely hydrogen bonds with his 57. —Preceding unsigned comment added by 71.108.24.11 (talk) 02:05, 28 November 2010 (UTC)

Shouldn't the mechanism have arrows for the reverse reaction? —Preceding unsigned comment added by 169.237.135.13 (talk) 06:01, 8 December 2010 (UTC)
