Peptidoglycan hydrolase LytB WW-like domain Structural analysis revealed that the catalytic domain of LytB consists of three structurally independent modules: SH3b, WW domain-like, and the glycoside hydrolase family 73 (GH73). This entry is the WW like domain found in endo-beta-N-acetylglucosaminidase LytB from Streptococcus pneumoniae. Functional analysis show that the deletion of both SH3b and WW modules almost completely abolished the activity of LytB. Furthermore, it was shown that the SH3b and WW modules are indispensable for LytB in cell separation. |
