Comments [?]

Function Murein-degrading enzyme that degrades murein glycan strands and insoluble, high-molecular weight murein sacculi, with the concomitant formation of a 1,6-anhydromuramoyl product. Lytic transglycosylases (LTs) play an integral role in the metabolism of the peptidoglycan (PG) sacculus. Their lytic action creates space within the PG sacculus to allow for its expansion as well as for the insertion of various structures such as secretion systems and flagella.
Catalytic activity Reaction=Exolytic cleavage of the (1->4)-beta-glycosidic linkage between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine (GlcNAc) residues in peptidoglycan, from either the reducing or the non-reducing ends of the peptidoglycan chains, with concomitant formation of a 1,6-anhydrobond in the MurNAc residue.; EC=4.2.2.n1;
Subcellular location Cell outer membrane; Peripheral membrane protein. Note=Attached to the inner leaflet of the outer membrane.
Domain The N-terminal domain does not have lytic activity and probably modulates enzymatic activity. The C-terminal domain is the catalytic active domain.
Similarity In the N-terminal section; belongs to the bacterial solute-binding protein 3 family.
In the C-terminal section; belongs to the transglycosylase Slt family.
