  • Title: Enzyme reactions and genes in aflatoxin biosynthesis.
    Author: Yabe K, Nakajima H.
    Journal: Appl Microbiol Biotechnol; 2004 Jun; 64(6):745-55. PubMed ID: 15022028.
    Abstract:
    Aflatoxins are highly toxic and carcinogenic substances mainly produced by Aspergillus flavus and Aspergillus parasiticus. Sterigmatocystin is a penultimate precursor of aflatoxins and also a toxic and carcinogenic substance produced by many species, including Aspergillus nidulans. Recently, the majority of the enzyme reactions involved in aflatoxin/sterigmatocystin biosynthesis have been clarified, and the genes encoding the enzymes have been isolated. Most of the genes constitute a large gene cluster in the fungal genome, and their expression is mostly regulated by a product of the regulatory gene aflR. This review will summarize the enzymatic steps and the genes in aflatoxin/sterigmatocystin biosynthesis.
