Abstract

Humidimycin (MDN-0010) is a ribosomally synthesized and post-translationally modified peptide (RiPP) belonging to class I lasso peptides, and is structurally related to siamycins, which have been shown to have strong antimicrobial activities against Gram-positive bacteria and to possess anti-HIV activity. Humidimycin was isolated from the strain Streptomyces humidus CA-100629, and was shown to synergize the activity of the fungal cell wall inhibitor caspofungin. In this work, the biosynthetic gene cluster of humidimycin was identified by genome mining of S. humidus CA-100629, cloned by Gibson assembly, and heterologously expressed. View Full-Text
