 | | Cyanobacteria and some of the γ-Proteobacteria appear to possess arsC genes that are similar to those of Low GC Gram-positive Bacteria, and other isolated taxa possess arsC genes that would not be expected based on known evolutionary relationships. |
| | At a basic level, these broad groupings of arsC correspond to the three distinct classes of arsenate reductases that others have observed [30], and these three groups had low sequence similarity to each other (less than 33% similarity between the Bacteria and Archaea/Eukarya, and 48% similarity between the two major bacterial groups). |
| | The two major groups of plasmid-borne genes are those of the Staphylococci (which were the first arsC genes to be recognized [17,18]) and those of the Enterobacteriales. |
