This entry represents a member of a biosynthetic gene cluster (BGC). This BGC (BGC0001905) is described by MIBiG as an example of the following biosynthetic class, polyketide. This family includes a protein from the violapyrone B biosynthetic gene cluster from Streptomyces somaliensis and appears to be predominantly found in Actinobacteria and Caudovirale bacteriophages [1].
