WebCitrinin (Figure 5(b)) is a low-molecular-weight ... Genes in black have been experimentally determined not to be involved in the biosynthesis of antimycins (Seipke & Hutchings, unpublished). The two overlapping cosmids, cosmid213 and cosmid456, are shown; // … 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. Mrl2 encodes a non heme Fe(II) dependent oxygenase (CitB) which is involved i…
