CC -!- FUNCTION: Catalyzes cross-linking of the peptidoglycan cell wall at the
CC division septum. {ECO:0000256|HAMAP-Rule:MF_02080}.
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; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_02080};
CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_02080}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_02080}; Single-pass membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_02080}.
CC -!- SIMILARITY: Belongs to the transpeptidase family. FtsI subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_02080}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
