Fig. 1From: Functional analysis of filipin tailoring genes from Streptomyces filipinensis reveals alternative routes in filipin III biosynthesis and yields bioactive derivativesComparison of filipin tailoring gene clusters from S. filipinensis and S. avermitilis. The size of the upstream region of each gene is indicated in nucleotides. Arrows indicate the organization of transcriptional units. The transcriptional organization of S. avermitilis has been included for comparison [9].Back to article page
