Producing organism
Streptomyces sp. YO15-A001
Biological activity
antifungal, inhibition of the FOF1-ATPase activity
A new antifungal compound YO-001A was found from the culture broth of Streptomyces sp. YO15-A001, which was isolated from a soil sample collected in Toyama Prefecture. YO-001A was identified through morphological changes-based screening of the rice blast fungus, Pyricularia oryzae (P. oryzae). YO-001A is a new 26-membered macrolide of the oligomycin family, which exhibits potent antifungal activity against P. oryzae with an IC50 of 0.012 µM by disrupting mitochondrial respiration via inhibition of the FOF1-ATPase activity.
