Protein

D-alanine--D-alanyl carrier protein ligase

Gene

dltA

Organism
Staphylococcus aureus (strain COL)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the first step in the D-alanylation of lipoteichoic acid (LTA), the activation of D-alanine and its transfer onto the D-alanyl carrier protein (Dcp) DltC. In an ATP-dependent two-step reaction, forms a high energy D-alanyl-AMP intermediate, followed by transfer of the D-alanyl residue as a thiol ester to the phosphopantheinyl prosthetic group of the Dcp. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram-positive bacteria, influencing the net charge of the cell wall.UniRule annotation

Catalytic activityi

D-alanine + ATP + holo-[D-alanyl-carrier protein] = AMP + diphosphate + D-alanyl-[D-alanyl-carrier protein].UniRule annotation
