[Reaction of poly(ADP)-ribosylation of histone H1 in the presence of P1,P4-bis(5'-adenosyl)tetraphosphate and its phosphonate analogs].
Effects of P1,P4-bis(5'-adenosyl)tetraphosphate and its phosphonate analogs on the ADP-ribosylation of H1 catalyzed by bovine testis ADP-ribose polymerase was investigated. Analogs App[CH(COCH3)]ppA and Ap[CH2]pppA as well as Ap4A inhibited poly(ADP)-ribosylation of histone H1 and at the same time accepted the ADP-ribosyl moiety of NAD. It was shown that inhibition of ADP-ribosylation of histone H1 is due to the competition of nucleotides with histone H1 for accepting ADP-ribosyl moiety of NAD on the one hand, and alteration of acceptor properties of the histone H1 on the other.
