Schematic representation of secondary metabolite gene clusters in Mic-PCC7806. (A) Gene clusters encoding non-ribosomal peptide synthetases (NRPS) and polyketide synthases (PKS). The names assigned to individual genes in Mic-PCC7806, or to genes that were characterized in other cyanobacterial strains are indicated above the arrows. Products assigned to the respective pathways are shown on the right. (B) Gene cluster encoding enzymes potentially involved in a patellamide-like pathway. Names of patellamide biosynthesis genes are indicated above the arrows. Gene identifiers in the Mic-PCC7806 genome are indicated below the arrows.
