CC -!- FUNCTION: Murein-degrading enzyme. May play a role in recycling of
CC muropeptides during cell elongation and/or cell division.
CC Preferentially cleaves at a distance of more than two disaccharide
CC units from the ends of the glycan chain. {ECO:0000255|HAMAP-
CC Rule:MF_01381}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endolytic cleavage of the (1->4)-beta-glycosidic linkage
CC between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine
CC (GlcNAc) residues in peptidoglycan with concomitant formation of a
CC 1,6-anhydrobond in the MurNAc residue.; EC=4.2.2.n2;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01381};
CC -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000255|HAMAP-
CC Rule:MF_01381}; Lipid-anchor {ECO:0000255|HAMAP-Rule:MF_01381}.
CC -!- SIMILARITY: Belongs to the transglycosylase Slt family.
CC {ECO:0000255|HAMAP-Rule:MF_01381}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAN42801.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC Sequence=AAP16689.1; Type=Erroneous initiation; Evidence={ECO:0000305};
