Glycoside Hydrolase Family 23

Activities in Familylysozyme type G (EC; peptidoglycan lyase (EC 4.2.2.n1) also known in the literature as peptidoglycan lytic transglycosylase; chitinase (EC
Mechanism Not known
Catalytic Nucleophile/BaseNot known
Catalytic Proton DonorGlu
NoteCorresponds to family 1 of the peptidoglycan lytic transglycosylases described by N.T. Blackburn and A.J. Clarke (2001) J. Mol. Evol. 52, 78-84; Note that 'peptidoglycan lytic transglycosylases' cleave peptidoglycan without intervention of a water molecule.
