Variants of the glycosyltransferases involved in synthesis of LOS outer core structures in C. jejuni strains BD-07, BD-10, BD-39 and BD-67a.

aAssignment of the glycosyltransferase variants is based on amino acid sequence comparisons with variants of known specificities.bon: indicates that a gene has no frame-shift mutation.cMono-sialyl.: the glycosyltransferase is specific for mono-sialylated acceptors.dNon-sialyl.: the glycosyltransferase is specific for non-sialylated acceptors.eoff: indicates that a gene is inactive because of a frame-shift mutation.fCst-II variants: mono-: monofunctional, Cst-II has α-2,3-sialyltransferase activity. bi-: bifunctional, Cst-II has both α-2,3-sialyltransferase and α-2,8-sialyltransferase activity.gGalT: β-1,4-galactosyltransferase that uses Glcβ-1,2-HepII- as acceptor.
