The deletion mutant of candicidins in Streptomyces sp. GF20 had weaker antifungal activities against Xylaria sp. and M. anisopliae. (A) HPLC profiles of the metabolites of wide type Streptomyces sp. GF20 and mutant GF20 ΔfscA. The asterisk symbols (*) denote homologs of candicidin. (B,C), paired challenge assays of GF20 and the deletion mutant (GF20 ΔfscA) against Xylaria sp. (Xa, B) and M. anisopliae (Ma, C). (D) HRMS spectrum of compound 5 from GF20. (E) The predicted structure of candicidin D (5).
