Comments [?]

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
