Fig 3.

Schematic representation and comparison of the GT-42 loci of different Helicobacter bizzozeronii strains. Empty arrows represent the direction of transcription of the open reading frames within each locus. Black boxes correspond to the positions of simple sequence repeats (SSRs) of cytosine or guanine. Black arrows indicate the insertion in the promoter region of the mini-IS. b, N-acetylneuraminic acid synthetase (neuB); c, UDP-N-acetylglucosamine-2-epimerase (neuC); a, CMP-sialic acid synthetase (neuA); s, sialyltransferase (with the corresponding phylogenetic group indicated).
