title: [Interactions of yeast hexokinase with ATP and AMP 4-(N-2-chloroethyl-N-methylamino)benzylamidates].
abstract: The interactions of ATP and AMP 4-(N-2-chloroethyl-N-methylamino)-benzylamidates with yeast hexokinase were studied. It was found that the ATP analog does not interact with hexokinase. The AMP analog irreversibly and almost completely inactivates hexokinse. A strong protective effect is exerted by MgATP. The value of apparent Ki for the AMP analog is equal to 2.10(4) M. The existence of affinity modification is postulated.
