pldA operon prediction. Operon prediction for clusters of orthologous groups (COGs) COG2829 (OMPLA; or pldA on gene-level) using ProOpDB where a illustrates a subset of proteobacteria, including H. pylori, E. coli and Yersinia pestis and b illustrates the Helicobacters found in the ProOpDB. Gastric Helicobacter bacteria are highlighted in blue. Each colour represents a COG, except grey which indicate genes with an unknown COG. Yellow represents pldA (COG2829); Na+-dependent AmCI and AmCII (COG0377) coloured green; dnaN (COG0592) coloured orange and gyrB (COG0187) coloured purple
