Citrinin is biosynthesized by fungi species of Penicillium, Monascus and Aspergillus. For the production of citrinin, a minimal set of genes is needed. These genes are conserved in most species which produce citrinin. They are citS, mrl1, mrl2, mrl4, mrl6, and mrl7. CitS produces a citrinin synthase (CitS). The product of the mrl1 gene is a serine hydrolase (CitA), but its function is not known yet.
