  1. Operon prediction comparing gastric and enterohepatic genes upstream/downstream from pldA. Helicobacter species. Operons are predicted by Fgenesb software (Softberry Inc., Mount Kisco, NY, US). COG0377 corresponds to the “Na+-dependent transporters (channels) of the SNF family” (this includes AmCI and AmCII). The COG0377 are phase variable genes
