Aspergillus nidulans is an excellent experimental organism for the study of gene regulation. Genetic and molecular analyses of trans-acting and cis-acting mutations have revealed a complex pattern of regulation involving multiple independent controls. Expression of the amdS gene is regulated by the facB and amdA genes which encode positively acting regulatory proteins mediating a major and a minor form of acetate induction respectively. The product of the amdR gene mediates omega amino acid induction of amdS. The binding sites for each of these proteins have been localised through amdS cis-acting mutations which specifically affect the interaction with the regulatory protein. The global cont..
