  • a We determined the phylum, genus, and species of bacteria that contained CZB domain proteins based on the NCBI Taxonomy Browser (http://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi). Note that only the first protein identification for each unique sequence was utilized for this analysis. Thus, organisms with identical protein sequences in multiple strains were counted only once. This is exemplified by E. coli, which has homologs in most strains, including K-12. This set is representative and not complete.
