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:0000256|ARBA:ARBA00002624,
CC ECO:0000256|PIRNR:PIRNR002799}.
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-
