title: Cyclic AMP and fructose-2,6-bisphosphate stimulated in vitro phosphorylation of yeast fructose-1,6-bisphosphatase.
abstract: Phosphorylation of purified yeast fructose-1,6-bisphosphatase was studied using purified preparations from yeast of two different cyclic AMP-independent protein kinases and a cyclic AMP-dependent protein kinase. Incorporation of 32P into fructose-1,6-bisphosphatase could be demonstrated only with the cyclic AMP-dependent protein kinase. Phosphorylation of fructose-1,6-bisphosphatase was stimulated by 3 microM fructose-2,6-bisphosphate and inhibited by 1 mM 5'-AMP.
