title: The rfaD gene codes for ADP-L-glycero-D-mannoheptose-6-epimerase. An enzyme required for lipopolysaccharide core biosynthesis.
abstract: The rfaD gene product, ADP-L-glycero-D-mannoheptose-6-epimerase, is necessary for the conversion of ADP-D-glycero-D-mannoheptose to ADP-L-glycero-D-mannoheptose. The nucleotide ADP-D-glycero-D-mannoheptose accumulates in rfaD mutant strains. Two chimeric colicin E1 plasmids carrying the coding sequence of the rfaD+ locus have been selected and shown to complement the rfaD phenotype. These clones also result in an amplification of ADP-L-glycero-D-mannoheptose-6-epimerase activity.
