Disease relevance of ECs4508

  • The mono-functional Kdo transferase of H. influenzae is membrane-bound, and the reaction is dependent upon a CMP-Kdo-generating system, as in E. coli [1].
  • 9. The identification of the mono-functional H. influenzae Kdo transferase, which is encoded by a KdtA homologue that displays 50% identity to its E. coli counterpart, should facilitate the mechanistic dissection of more complex multi-functional Kdo transferases, like those of E. coli and Chlamydia trachomatis [1].

Chemical compound and disease context of ECs4508

 

Biological context of ECs4508

  • A plasmid from the Clarke and Carbon collection (Clarke, L., and Carbon, J. (1976) Cell 9, 91-99), pLC17-24, known to contain genes from the rfa region (81 min), was shown to overexpress KDO transferase activity 4-5 times and to correct the mutation when the plasmid was conjugated into the mutant strains [5].
  • Synthetic lipid A analogues varying in the acylation or phosphorylation pattern or both were tested as acceptors for the subsequent transfer of 3-deoxy-Dmanno-oct-2-ulosonic acid (Kdo) and heptose by successive action of Kdo transferase (WaaA), heptosyltransferase I (WaaC) and heptosyltransferase II (WaaF) [6].
  • GseA is similar, and in a few stretches identical, in its amino acid sequence to KdtA, an Escherichia coli Kdo transferase [7].
