Abstract:
Massilia sp. NR 4-1 was a violacein producing strain newly isolated from topsoil under nutmeg tree, Torreya nucifera in Korean national monument Bijarim Forest. Violacein is a novel class of drug exhibiting anticancer and antibiotic activities originated from l-tryptophan. Here, we present the complete genome of Massilia sp. strain NR 4-1 of 6,361,416bp and total 5285 coding sequences (CDSs) including a complete violacein biosynthesis pathway, vioABCDE. The genome sequence of Massilia sp. NR 4-1 will provide stable and efficient biotechnological applications of violacein production.
