By enticing away the repressors dampening unexpressed, silent genes in Streptomyces bacteria, researchers at the have unlocked several large gene clusters for new natural products. Since many antibiotics, anti-cancer agents and other drugs have been derived from genes readily expressed in Streptomyces, the researchers hope that unsilencing genes that have not previously been expressed in the lab will yield additional candidates in the search for new antimicrobial drugs.
