FUNCTION	Catalyzes cross-linking of the peptidoglycan cell wall at the division septum.
CATALYTIC ACTIVITY	Reaction=Preferential cleavage: (Ac)2-L-Lys-D-Ala-\|-D-Ala. Also transpeptidation of peptidyl-alanyl moieties that are N-acyl substituents of D-alanine.; EC=3.4.16.4;
PATHWAY	Cell wall biogenesis; peptidoglycan biosynthesis.
case <Feature:Transmembrane==1>
SUBCELLULAR LOCATION	Cell inner membrane; Single-pass membrane protein.
end case
SIMILARITY	Belongs to the transpeptidase family. FtsI subfamily.

Fusion	Nter: None Cter: None
Comments	Second copy in Pseudomonas aeruginosa (penicillin-binding protein 3 homolog), which has probably the same catalytic activity. Does not match FTSI_CAUVN, which seems divergent.
