Question
Put these steps in the mechanism of chymotrypsin catalysis in order from first to last. Note there are 8 steps. -His 57 catalyzes removal of H from Ser 195 hydroxyl. -Ser 195's nucleophilic O attacks carbonyl C of substrate. -His 57 donates H to N of sissile peptide bond, tetrahedral intermediate decomposes. -C- terminal portion of oribinal substrate with its new amino acid terminus diffuses away. -Water donates H to His 57. -Resulting OH attacks carbonyl of remaining substrate. -His 57 donates H to Ser 195 O, leading to collapse of tetrahedral intermediate. -N-terminal portion of original substrate with its new carboxy terminus diffuses away.Explanation / Answer
this is incorrect...
