Name  Coenzyme A biosynthesis protein Short Name  LPS_biosynth
Type  Family Description  Temperature-sensitive mutants of Escherichia coli, defective in the transfer of 3-deoxy-D-manno-octulosonic acid (KDO) from CMP-KDO to a tetraacyldisaccharide 1,4'-bisphosphate precursor of lipid A, have been used to map KDO transferase activity on the E. coli chromosome []. The KDO transferase gene, designated kdtA, was shown to code for a 43kDa polypeptide. Overexpression of this single gene product greatly stimulates incorporation of two stereochemically distinct KDO residues during lipopolysaccharide biosynthesis in extracts of E. coli [].From these experiments this protein was thought to play a role in lipopolysaccharide biosynthesis, however now it is annotated as phosphopantetheine adenylyltransferase (), which catalyses the reversible transfer of an adenylyl group from ATP to 4'-phosphopantetheine to give dephospho-CoA (DPCOA) and pyrophosphate in the fourth (and penultimate) step of coenzyme A biosynthesis [].
