The genome of the insecticidal Chromobacterium subtsugae PRAA4-1 and its comparison with that of Chromobacterium violaceum ATCC 12472.
The genome of Chromobacterium subtsugae strain PRAA4-1, a betaproteobacterium producing insecticidal compounds, was sequenced and compared with the genome of C. violaceum ATCC 12472. The genome of C. subtsugae displayed a reduction in genes devoted to capsular and extracellular polysaccharide, possessed no genes encoding nitrate reductases, and exhibited many more phage-related sequences than were observed for C. violaceum. The genomes of both species possess a number of gene clusters predicted to encode biosynthetic complexes for secondary metabolites; these clusters suggest they produce overlapping, but distinct assortments of metabolites.
