[The mechanism of action of trisportic acids on the carotene-synthesizing enzymes of the (-) strain of Blakeslea trispora].

Trisporic acids were found to increase the content of carotene, protein, and RNA in the (-)strain of Blakeslea trispora. Trisporic acids are inductors of the synthesis of carotenogenous enzymes as was found in experiments with the inhibitor of transcription (cycloheximide) and translation (actinomycin D). Trisporic acids stimulate the formation of neutral fractions of the sex hormone, the process being regulated presumably at the level of posttranscription control.
