FUNCTIONCatalyzes 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;
PATHWAYCell wall biogenesis; peptidoglycan biosynthesis.
case <Feature:Transmembrane==1>
SUBCELLULAR LOCATIONCell inner membrane; Single-pass membrane protein.
end case
SIMILARITYBelongs 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.
