Glycoside Hydrolase Family 73

Activities in Familylysozyme (EC 3.2.1.17); mannosyl-glycoprotein endo-β-N-acetylglucosaminidase (EC 3.2.1.96); peptidoglycan hydrolase with endo-β-N-acetylglucosaminidase specificity (EC 3.2.1.-)
Mechanism Not known
3D Structure Statuslysozyme-type
Catalytic Nucleophile/BaseNot known
Catalytic Proton DonorGlu
NoteThe 3-D structure of Sphingomonas sp. strain A1 FlgJ protein of this family has recently been solved (Hashimotoa et al., BBRC 2009, in press); there is only one, unconfirmed, report of b-1,4-N-acetylmuramoylhydrolase (EC 3.2.1.17) activity
