Effect of adenosine 5'-monophosphate on adenosine 5'-triphosphate activation of methyl coenzyme M methylreductase in cell extracts of Methanosarcina barkeri.

D O Mountfort.   

Abstract

In cell extracts of Methanosarcina barkeri, adenosine 5'-triphosphate (ATP)-activated methyl coenzyme M methylreductase was inhibited by adenosine 5'-monophosphate (AMP) but not by cyclic AMP. AMP (2 and 4 mM) shifted the saturation curve for ATP activation from hyperbolic (Hill coefficient [n] = 1.0) to sigmoidal (n = 1.5), decreased Vmax, and increased the apparent KmATP.
