sporangiospore maturation cell wall hydrolase GsmA. The peptidoglycan-hydrolyzing enzyme GsmA occurs in some sporangia-forming members of the Actinobacteria, such as Actinoplanes missouriensis, and is required for proper separation of spores. GsmA proteins have one or two SH3 domains N-terminal to the hydrolase domain.
Mannosyl-glycoprotein endo-beta-N-acetylglucosaminidase. This family includes Mannosyl-glycoprotein endo-beta-N-acetylglucosaminidase EC:3.2.1.96. As well as the flageller protein J that has been shown to hydrolyze peptidoglycan.
CHAP domain. This domain corresponds to an amidase function. Many of these proteins are involved in cell wall metabolism of bacteria. This domain is found at the N-terminus of Escherichia coli gss, where it functions as a glutathionylspermidine amidase EC:3.5.1.78. This domain is found to be the catalytic domain of PlyCA. CHAP is the amidase domain of bifunctional Escherichia coli glutathionylspermidine synthetase/amidase, and it catalyzes the hydrolysis of Gsp (glutathionylspermidine) into glutathione and spermidine.
