Hierarchic Classification of Catalytic Mechanisms


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

L 1.30.-.- : C-O bond (O-glycoside bond) (Ligand group involved)

C 1.30.35885.- : beta-xylosidase-like mechanism (Nucleophile/Acid-Base/Modulator-Stabilizer/Modulator/Stabilizer); Modulation of nucleophile & acid-base; Acid protonation to leaving group leads to transition-state; Stabilization of transition-state; Nucleophilic attack forms intermediate; Base deprotonation of water; Activated water attacks on intermediate; SN1-like reaction (Catalytic mechanism)

P 1.30.35885.972 : Two acidic residues + Arg/His/Tyr + Asn or Gln (Residues/cofactors in Protein)


1st Nucleophile : a catalytic residue
Catalytic groups : groups in residue/substrate
General Base : a catalytic residue
