p-815 mouse mastocytoma cells express the k isozyme of pyruvate kinase and the specific activity of this enzyme is increased in response to n6,2'-o-dibutyryladenosine 3':5'-cyclic monophosphate , 8-bromoadenosine 3':5'-cyclic monophosphate , cholera toxin , and epinephrine , all of which also elevate the intracellular concentration of adenosine 3':5'-cyclic monophosphate .
