Hierarchic Classification of Catalytic Mechanisms


R 1.-.-.- : Hydrolysis (bond cleavage by water) (Reaction)

L 1.32.-.- : C-O bond (O-glycoside bond) close to N-acetyl group (Ligand group involved)

C 1.32.68200.- : Chitobiase-like mechanism (Acid-Base/Modulator-Stabilizer); Modulator-assisted acid protonation to leaving group leading to transition state; Modulator-assisted substrate nucleophilic attack on transition state leading to intermediate formation; Intermediate stabilization; Base-activated water attacks on intermediate leading to transition state; Bond cleavage of transision state; SN1-like reaction (Catalytic mechanism)
