CC   -!- FUNCTION: Murein-degrading enzyme. May play a role in recycling of
CC       muropeptides during cell elongation and/or cell division.
CC       {ECO:0000255|HAMAP-Rule:MF_01616}.
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_01616};
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01616}; Lipid-anchor {ECO:0000255|HAMAP-Rule:MF_01616}.
CC   -!- SIMILARITY: Belongs to the transglycosylase Slt family.
CC       {ECO:0000255|HAMAP-Rule:MF_01616}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABR78792.1; Type=Erroneous initiation; Evidence={ECO:0000305};
