1
The arrows indicate the organization of the genes. ECF, gene encoding an ECF41 σ factor; COE, gene encoding a carboxymuconolactone decarboxylase, oxidoreductase, or epimerase; ungrouped, genomic context differs from the above-mentioned groups and contains genes encoding hypothetical proteins of unknown function.
2
“-”, no promoter occurs upstream of the gene; n.a., the corresponding gene is not present or was omitted from analysis in case of ungrouped genomic context.
