Hierarchic Classification of Catalytic Mechanisms


R 3.-.-.- : Transfer (bond cleavage and new bond formation) (Reaction)

L 3.900.-.- : Glycosyl group from Hydroxyl oxygen to Hydroxyl oxygen (Ligand group involved)

C 3.900.45300.- : Anhydrosialidase-like mechanism (Acid-Base-Stabilizer/Stabilizer/Modulator); SN1-like reaction; Modulator assists bond cleavage between transferred group and leaving group; Acid protonation to leaving group leads to departure of leaving group; Intermediate (transferred group) stabilized; Base-activation of acceptor group; Activated acceptor attacks on transferred group (Catalytic mechanism)

P 3.900.45300.71 : Asp/Glu/Tyr (Residues/cofactors in Protein)


1st Nucleophile : an acceptor group in substrate
Catalytic groups : groups in residue/substrate
General Base : a catalytic residue
General Acid : a catalytic residue
