Modification of the lipid A moiety of lipopolysaccharide by the addition, of the sugar 4-amino-4-deoxy-L-arabinose (L-Ara4N) is a strategy adopted, by pathogenic Gram-negative bacteria to evade cationic antimicrobial, peptides produced by the innate immune system. L-Ara4N biosynthesis is, therefore a potential anti-infective target, because inhibiting its, synthesis would render certain pathogens more sensitive to the immune, system. The bifunctional enzyme ArnA, which is required for L-Ara4N, biosynthesis, catalyzes the NAD(+)-dependent oxidative decarboxylation of, UDP-glucuronic acid to generate a UDP-4'-keto-pentose sugar and also, catalyzes transfer of a formyl group from N-10-formyltetrahydrofolate to, the 4'-amine of UDP-L-Ara4N. We now report the crystal structure of the, ... [[http://ispc.weizmann.ac.il/pmbin/getpm?15809294 (full description)]]
