-
the bifunctional enzyme transfers two 3-deoxy-D-manno-octulosonate residues to lipid A precursors or analogs bearing four to six fatty acyl chains and a 4-monophosphate moiety. Key enzyme in lipopolysaccharide biosynthesis. (KDO)-lipid IV(A) = 3-deoxy-alpha-D-manno-oct-2-ulopyranosyl-(2->6)-2-deoxy-2-[[(3R)-3-hydroxypentadecanoyl]amino]-3-O-[(3R)-3-hydroxytetradecanoyl]-4-O-phosphono-beta-D-glucopyranosyl-(1->6)-2-deoxy-3-O-[(3R)-3-hydroxytetradecanoyl]-2-[[(3R)-3-hydroxytetradecanoyl]amino]-1-O-phosphono-alpha-D-glucopyranose. (KDO)2-lipid IV(A) = 3-deoxy-alpha-D-manno-oct-2-ulopyranosyl-(2->4)-3-deoxy-alpha-D-manno-oct-2-ulopyranosyl-(2->6)-2-deoxy-2-[[(3R)-3-hydroxypentadecanoyl]amino]-3-O-[(3R)-3-hydroxytetradecanoyl]-4-O-phosphono-beta-D-glucopyranosyl-(1->6)-2-deoxy-3-O-[(3R)-3-hydroxytetradecanoyl]-O-[[(3R)-3-hydroxytetradecanoyl]amino]-1-O-phosphono-alpha-D-glucopyranose

malfunction
physiological function
-
the main function of Kdo transferase is to provide the right substrates for the acyltransferases LpxL and LpxM, resulting in the synthesis of penta- and hexaacylated lipid A, which is optimal for the MsbA flippase
malfunction
-
construction of a kdtA::kan insertion mutation, using a gene replacement method. Growth of this strain is absolutely dependent upon the presence of a functional copy of the kdtA gene (or the related gseA gene) carried on a plasmid
malfunction
-
kdtA deletion mutants are viable when lpxL and lpxM (the lauroyl- or the myristoyltransferase of lipid A biosynthesis) are overexpressed. Deletion of kdtA in strains overexpressing LpxM causes accumulation of pentaacylated lipid A with a secondary myristate moiety. None of the strains lacking kdtA grow in the presence of bile salts at any temperature or on nutrient broth at 42°C
malfunction
-
waaA (monofunctional Kdo transferase) of Haemophilus influenzae can not complement a knockout mutation in the corresponding gene of an Re-type Escherichia coli strain (encoding a bifunctional enzyme that transfers two 3-deoxy-D-manno-octulosonate residues to the lipid A precursor). However, complementation is possible by coexpressing the recombinant waaA together with the LPS-specific KDO kinase gene (kdkA) of Haemophilus influenzae DSM11121 or I69, respectively
