Description
Sterigmatocystin is a mycotoxin produced by several species of aspergillus. It is structurally related to the aflatoxins. It is mutagenic, teratogenic and carcinogenic and is less widespread and potent than Aflatoxin. It inhibits acyl-CoA. It is a cholesterol acyltransferase (ACAT) with selectivity for the ACAT2 isoenzyme.
