Function
function
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.
Catalytic activity
- ATP + D-alanine + holo-[D-alanyl-carrier protein] = AMP + D-alanyl-[D-alanyl-carrier protein] + diphosphate
Pathway
Cell wall biogenesis; lipoteichoic acid biosynthesis.
