LITERATURE
gene kdnA, encoded in the Kdo8N biosynthetic cluster, DNA and amino acid sequence determination and analysis, subcloning and expression in Escherichia coli strains EC100D and WBB06 at 37°C, recombinant expression of the gene cluster for 8-amino-3,8-dideoxy-D-manno-octulosonic acid biosynthesis from Shewanella oneidensis in Escherichia coli results in lipid A containing 8-amino-3,8-dideoxy-D-manno-octulosonic acid, and in vitro assays confirm the enzymatic functionality converting 3-deoxy-D-manno-octulosonic acid to 8-amino-3,8-dideoxy-D-manno-octulosonic acid, with incorporation into the Kdo8N-lipid A domain of lipopolysaccharide by a metal-dependent oxidase followed by a glutamate-dependent aminotransferase, recombinant expression of His-tagged enzyme in Escherichia coi strain C41
