CC -!- FUNCTION: Endohydrolysis of the di-N-acetylchitobiosyl unit in high-
CC mannose glycopeptides and glycoproteins containing the
CC -[(Man)5(GlcNAc)2]-Asn structure. One N-acetyl-D-glucosamine residue
CC remains attached to the protein; the rest of the oligosaccharide is
CC released intact. Cleaves the peptidoglycan connecting the daughter
CC cells at the end of the cell division cycle, resulting in the
CC separation of the two newly divided cells. Acts as an autolysin in
CC penicillin-induced lysis (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolyzes the link between N-acetylmuramoyl residues and L-
CC amino acid residues in certain cell-wall glycopeptides.; EC=3.5.1.28;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endohydrolysis of the N,N'-diacetylchitobiosyl unit in high-
CC mannose glycopeptides and glycoproteins containing the
CC -[Man(GlcNAc)2]Asn- structure. One N-acetyl-D-glucosamine residue
CC remains attached to the protein, the rest of the oligosaccharide is
CC released intact.; EC=3.2.1.96;
CC -!- SUBUNIT: Oligomer; forms a ring structure at the cell surface which is
CC important for efficient partitioning of daughter cells after cell
CC division. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Note=Secreted, and then
CC anchored on the cell surface at the peripheral cell wall above the
CC completed septum (septal region), for the next cell division cycle.
CC {ECO:0000250}.
CC -!- DOMAIN: The GW domains are responsible for directing the proteins to
CC the septal region. {ECO:0000250}.
CC -!- PTM: Undergoes proteolytic processing to generate the two extracellular
CC lytic enzymes, probably at the septal region on the cell surface.
CC {ECO:0000250}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the N-acetylmuramoyl-
CC L-alanine amidase 2 family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the glycosyl
CC hydrolase 73 family. {ECO:0000305}.
