Abstract
1. Evidence is presented that cyclic AMP inhibits the incorporation of l-[4,5-(3)H]leucine into protein in a cell-free system from rat liver. This inhibition occurs after aminoacyl-tRNA formation. 2. Microsomal fractions, isolated after the incubation of postmitochondrial supernatant with cyclic AMP and ATP, show a diminished ability to synthesize protein. Both cyclic AMP and ATP are required for this effect. 3. A possible physiological role for the anti-anabolic action of cyclic AMP is discussed in terms of the control of gluconeogenesis.
