Adenylate Kinase from Maize Leaves: True Substrates, Inhibition by P^P^d^adenosine-S'Jpentaphosphate and Kinetic Mechanism


Purified maize leaf adenylate kinase (AK) was shown to use one molecule each of free ADP and Mg-ADP as well as free AMP and Mg-ATP as substrates in the forward and reverse reac­ tion, respectively. This was deduced from substrate kinetic studies which were carried out un­ der conditions of strictly defined concentrations of free and Mg-complexed adenylate… (More)
