CC   -!- FUNCTION: Cell wall formation. Synthesis of cross-linked
CC       peptidoglycan from the lipid intermediates. The enzyme has a
CC       penicillin-insensitive transglycosylase N-terminal domain
CC       (formation of linear glycan strands) and a penicillin-sensitive
CC       transpeptidase C-terminal domain (cross-linking of the peptide
CC       subunits). {ECO:0000256|PIRNR:PIRNR002799}.
CC   -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC       {ECO:0000256|PIRNR:PIRNR002799}.
CC   -!- SIMILARITY: In the C-terminal section; belongs to the
CC       transpeptidase family. {ECO:0000256|PIRNR:PIRNR002799}.
CC   -!- SIMILARITY: In the N-terminal section; belongs to the
CC       glycosyltransferase 51 family. {ECO:0000256|PIRNR:PIRNR002799}.
