title: Regulation of aflatoxin biosynthesis: effect of adenine nucleotides, cyclic AMP and N6-O2' -dibutyryl cyclic AMP on the incorporation of (1-14C)-acetate into aflatoxins by Aspergillus parasiticus NRRL-3240.
abstract: Adenosine triphosphate (ATP) was found to inhibit the incorporation of labelled acetate into aflatoxins while adenosine diphosphate (ADP) and adenosine monophosphate (AMP) stimulated the process. Exogenous cyclic AMP and its derivative, N6-O2' -dibutyryl cyclic AMP produced efficient (1-14C)-acetate incorporation into aflatoxins at all the concentrations tried (0.1, 0.5 and 1 mM). The stimulation of incorporation of labelled acetate into aflatoxins was significant at 0.1 and 1 mM concentration of the cyclic nucleotide but was found to be maximum at 0.5 mM concentration.
