malfunction
metabolism
the enzyme is involved in the synthesis of a mitochondrial not yet identified lipid A-like molecule rather than in the synthesis of the cell wall rhamnogalacturonan II
physiological function
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
physiological function
-
chlamydial KDO transferases can replace in Escherichia coli K-12 the host's KDO transferase and retain the product specificities described in their natural background. WaaA from Chlamydia psittaci transfers predominantly four KDO residues to lipid A, forming a branched tetrasaccharide with the structure alpha-KDO-(2,8)-[alpha-KDO-(2,4)]-alpha-KDO-(2,4)-alpha-KDO
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
physiological function
-
chlamydial KDO transferases can replace in Escherichia coli K-12 the host's KDO transferase and retain the product specificities described in their natural background. WaaA from Chlamydia psittaci transfers predominantly four KDO residues to lipid A, forming a branched tetrasaccharide with the structure alpha-KDO-(2,8)-[alpha-KDO-(2,4)]-alpha-KDO-(2,4)-alpha-KDO

expressed in a rough mutant (Re chemotype) of Escherichia coli (strain F515) that contains an lipopolysaccharide with only two alpha 2-4-linked Kdo residues. Recombinant strains are able to add the immunodominant Kdo residue in alpha 2-8-linkage to the parental lipopolysaccharide.

expression in Escherichia coli. Chlamydial Kdo transferases can replace in Escherichia coli K-12 the host's Kdo transferase and retain the product specificities described in their natural background. WaaA from Chlamydia psittaci transfers predominantly four Kdo residues to lipid A, forming a branched tetrasaccharide with the structure alpha-Kdo-(2,8)-[alpha-Kdo-(2,4)]-alpha-Kdo-(2,4)-alpha-Kdo
-
introduction of gseA into an Escherichia coli mutant with a thermolabile kdtA gene product endows cell extracts with the ability to transfer not only the third but also the first two Kdos to lipid A precursors, the Chlamydia trachomatis enzyme is at least trifunctional
