Genome context of UlaG in bacterial genomes. True orthology between similar sequences often requires conservation of the gene's genomic context, especially in the context of gene clusters encoding for signal transduction cascades or metabolic pathways. The genome context around ulaG-like genes in >100 bacterial genomes (including many genomes from human symbiotic bacteria and pathogens) was examined. For clarity, only a representative set of consistent genomic arrangements is shown. Arrows represent the gene order and orientation of the transcription of each per species. Dashed lines connecting arrows represent larger intergenic spaces accommodating transcription regulatory sequences. Relevant taxonomic groupings are shown.
