[Interaction of thiamine pyrophosphokinase from brewer's yeast with thiamine and adenosine-5'-triphosphate].
The interaction of thiamine pyrophosphokinase (Thiaminkinase EC 2.7.6.2) with thiamine and ATP was studied. It was shown that the mechanism of the thiaminokinase reactions is Rapid Equilibrium Random Bi -- Bi. The enzyme binds 8 moles ATP and 1 mole thiamine per mole protein Ks = 0,8-10(-3) and 4.10(-6) M for ATP and thiamine respectively.
