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}.
