Chromobacterium violaceum, a Gram-negative β-proteobacterium, is a species of free-living microorganisms found in soil and water. In addition to providing fundamental insights into environmental adaption strategies, genomes of these bacteria can also provide a rich source of genes with biotechnological potential and medical utility. For instance, C. violaceum produces a natural antibiotic called violaceine that has been shown to be useful for the treatment of colon and other cancers (Kodach et al. 2006). The complete genome sequence of C. violaceum was identified by the Brazilian National Genome Sequencing Consortium in 2003 (Brazilian National Genome Project 2003). Their study showed that there were 4,431 uniformly distributed predicted protein coding ORFs, and 958 (21.6 %) of these were identified as conserved hypothetical proteins. Among them, protein CV_0373 from C. violaceum(UniProtKB entry Q7P141, gi 34101683, KEGG entry cvi:CV_0373) is annotated as a...
