Ligands: MG, PNS Related: 4bpf, 4bpg Activity: D-alanine--poly(phosphoribitol) ligase, with EC number 6.1.1.13 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [DLTC_BACSU] Involved in the biosynthesis of D-alanyl-lipoteichoic acid (LTA). Activated D-alanyl-Dcp donates its D-alanyl substituent to membrane-associated LTA. Publication Abstract from PubMed d-Alanylation of lipoteichoic acids plays an important role in modulating the properties of Gram-positive bacteria cell walls. The d-alanyl carrier protein DltC from Bacillus subtilis has been solved in apo- and two cofactor-modified holo-forms, whereby the entire phosphopantetheine moiety is defined in one. The atomic resolution of the apo-structure allows delineation of alternative conformations within the hydrophobic core of the 78 residue four helix bundle. In contrast to previous reports for a peptidyl carrier protein from a non-ribosomal peptide synthetase, no obvious structural differences between apo- and holo-DltC forms are observed. Solution NMR spectroscopy confirms these findings and demonstrates in addition that the two forms exhibit similar backbone dynamics on the ps-ns and ms timescales. High-resolution structures of the d-alanyl carrier protein (Dcp) DltC from Bacillus subtilis reveal equivalent conformations of apo- and holo-forms.,Zimmermann S, Pfennig S, Neumann P, Yonus H, Weininger U, Kovermann M, Balbach J, Stubbs MT FEBS Lett. 2015 Jul 17. pii: S0014-5793(15)00587-6. doi:, 10.1016/j.febslet.2015.07.008.
