Recombinant Bacillus subtilis D-alanine--D-alanyl carrier protein ligase (dltA)
Description
Purity > 85% as determined by SDS-PAGE. MW: 59.8kDa. Full Length: 1-503aa. N-terminal 6xHis-tagged. Bacillus subtilis (strain 168). 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.
