CC -!- FUNCTION: Cell wall formation. Synthesis of cross-linked peptidoglycan
CC from the lipid intermediates. The enzyme has a penicillin-insensitive
CC transglycosylase N-terminal domain (formation of linear glycan strands)
CC and a penicillin-sensitive transpeptidase C-terminal domain (cross-
CC linking of the peptide subunits). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-
CC Ala)](n)-di-trans,octa-cis-undecaprenyl diphosphate + beta-D-GlcNAc-

CC cis-undecaprenyl diphosphate = [GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-
CC D-Glu-L-Lys-D-Ala-D-Ala)](n+1)-di-trans-octa-cis-undecaprenyl
CC diphosphate + di-trans,octa-cis-undecaprenyl diphosphate + H(+);

CC ChEBI:CHEBI:78435; EC=2.4.1.129;
CC Evidence={ECO:0000250|UniProtKB:P02918};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Preferential cleavage: (Ac)2-L-Lys-D-Ala-|-D-Ala. Also
CC transpeptidation of peptidyl-alanyl moieties that are N-acyl
CC substituents of D-alanine.; EC=3.4.16.4;
CC Evidence={ECO:0000250|UniProtKB:P02918};
CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Single-pass type II
CC membrane protein {ECO:0000305}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the
CC glycosyltransferase 51 family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the transpeptidase
CC family. {ECO:0000305}.
