This entry represents a member of a biosynthetic gene cluster (BGC). This BGC (BGC0001016) is described by MIBiG as an example of the following biosynthetic classes, NRP (non-ribosomal peptide) and polyketide. This family includes a protein from then microcystin biosynthetic gene cluster from Anabaena sp. 90 [1].
