Protein Domain : IPR000189

Type:  Active_site Name:  Prokaryotic transglycosylase, active site
Description:  Bacterial lytic transglycosylases degrade murein via cleavage of the beta-1,4- glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine, with theconcomitant formation of a 1,6-anhydrobond in the muramic acid residue. Escherichia colihas at least three different lytic transglycosylases: two soluble isozymes of 65 Kd and 35 Kd and a membrane-bound enzyme of 38 Kd. Thesequence of the 65 Kd enzyme (gene slt) has been determined []. A domain ofabout 90 residues located near the C-terminal section of slt was recently shown to be present in a number of other prokaryotic and phage proteins [].This SLT domain shared by these proteins is involved in catalytic activity. The most conserved part of this domain contains the contains two conserved serines and aglutamate which form part of this active site signature [, ]. Short Name:  Transglyc_AS
