Glycoside Hydrolase Family 23

Activities in FamilyChitinase (EC 3.2.1.14);
Lysozyme (EC 3.2.1.17);
Peptidoglycan lytic transglycosylase / peptidoglycan lyase (EC 4.2.2.29);
Mechanism Unknown e
3D Structure Statuslysozyme fold
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.
