[Affinity modification of Escherichia coli Dna-polymerase I by 4-(N-2-chloroethyl-N-methylamino)-benzyl-gamma-amides of dTTP and dATP].
The interaction of dTTP and dATP gamma-4-(N-2-chloroethyl-N-methylamino) benzylamidates with E. coli DNA-polymerase I were studied. dTTP and dATP gamma-4-(N-2-hydroxyethyl-N-methylamino) benzylamidates act as competitive inhibitors of DNA-polymerase I. Ki values for gamma-analogues of dTTP and dATP have been determined. Reactive dTTP and dATP derivatives are shown to be affinity reagent for this enzyme.
