Identification and sequences of the lipopolysaccharide core biosynthetic genes rfaQ, rfaP, and rfaG of Escherichia coli K-12.

Abstract excerpt

The rfa locus of Escherichia coli K-12 includes a block of about 10 closely spaced genes transcribed in the same direction which are involved in synthesis and modification of the hexose region of the lipopolysaccharide core. We have sequenced the first three genes in this block. The function of the first of these genes is unknown, but we have designated it rfaQ on the basis of its location and similarity to other...
