title: [Action of an ATP analog, adenosine 5'-hyophosphophosphate in the reactions catalysed by hexokinase and fructose-6-phosphate kinase].
abstract: Adenosine 5'-hypoposphate phosphorylates glucose and fructose 6-phosphate in the presence of hexokinase and fructose 6-phosphate kinase respectively. It behaves as a competitive inhibitor versus ATP in the hexokinase reaction. Its affinity for the two enzymes is similar to that of ATP, the maximal velocities being however much lower.
