CC -!- FUNCTION: Murein-degrading enzyme that degrades murein glycan strands
CC and insoluble, high-molecular weight murein sacculi, with the
CC concomitant formation of a 1,6-anhydromuramoyl product. Lytic
CC transglycosylases (LTs) play an integral role in the metabolism of the
CC peptidoglycan (PG) sacculus. Their lytic action creates space within
CC the PG sacculus to allow for its expansion as well as for the insertion
CC of various structures such as secretion systems and flagella.
CC {ECO:0000255|HAMAP-Rule:MF_02016}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Exolytic cleavage of the (1->4)-beta-glycosidic linkage
CC between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine
CC (GlcNAc) residues in peptidoglycan, from either the reducing or the
CC non-reducing ends of the peptidoglycan chains, with concomitant
CC formation of a 1,6-anhydrobond in the MurNAc residue.; EC=4.2.2.n1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_02016};
CC -!- SUBCELLULAR LOCATION: Cell outer membrane; Peripheral membrane protein.
CC Note=Attached to the inner leaflet of the outer membrane.
CC {ECO:0000255|HAMAP-Rule:MF_02016}.
CC -!- DOMAIN: The N-terminal domain does not have lytic activity and probably
CC modulates enzymatic activity. The C-terminal domain is the catalytic
CC active domain. {ECO:0000255|HAMAP-Rule:MF_02016}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the bacterial solute-
CC binding protein 3 family. {ECO:0000255|HAMAP-Rule:MF_02016}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the transglycosylase
CC Slt family. {ECO:0000255|HAMAP-Rule:MF_02016}.
