ABSTRACT
The D-alanyl lipoteichoic acids (D-alanyl LTAs) present in the cell walls of Gram-positive bacteria play crucial roles in autolysis, cation homeostasis and biofilm formation. The alanylation of LTAs requires the D-alanyl carrier protein DltC to transfer D-Ala onto a membrane-associated LTA. Here, DltC from Staphylococcus epidermidis (SeDltC) was purified and crystallized using the sitting-drop vapour-diffusion method. The crystals diffracted to a resolution of 1.83â
Å and belonged to space group P2, with unit-cell parameters a = 66.26, b = 53.28, c = 88.05â
Å, ß = 98.22°. The results give a preliminary crystallographic analysis of SeDltC and shed light on the functional role of DltC in the alanylation of LTAs.
