Abstract
Currently, corticosteroids are the most potent anti-inflammatory drugs on the market. Here, we announce the draft genome sequence of the marine-derived Streptomyces sp. strain CNQ431, which produces cytokine inhibitors, termed splenocins, which display potent suppression of cytokine production at a comparable level to that of corticosteroids. The genome is approximately 498,750 bp with 72.03% G+C content.
