Hierarchic Classification of Catalytic Mechanisms


R 6.-.-.- : Exchange of double-bonded atoms (Schiff-base related reaction) (Reaction)

L 6.20.-.- : Schiff-base nitrogen to Carbonyl oxygen (Schiff-base deformation; hydration) (Ligand group involved)

C 6.20.85210.- : Base/Acid/Modulator; Base-activated substituted group attacks on double-bond partner atom; Acid protonation to leaving group; Formation of tetrahedral intermediate; 2nd base deprotonation of substituted group; Lone pair on nucleophile attacks again on double-bond partner atom; Proton transfer from protonated base to deprotonated acid through cofactor/modulator and water; Organic-cofactor-assisted reaction (Catalytic mechanism)


1st Nucleophile : Substituted group (substrate or water)
Catalytic groups : cofactor + groups in residue/substrate
General Base : a catalytic residue
General Acid : a catalytic residue
