[Apurinic-apyrimidinic DNA-endonuclease activity of cytochrome c and pancreatic RNAse].
Cationic proteins--cytochrome c and pancreatic RNAase--possess the apurinic-apyrimidinic DNA-endonuclease activity. The affinity of these proteins for DNA-apurinic sites does not differ from that of specific apurinic DNA-endonucleases described in literature. The main features of the apurinic activity of cationic proteins are as follows: low specific activity, high temperature optimum of the reaction, absence of primer-stimulated activity. The feasibility of participation of cationic proteins and some other nucleophilic compounds in single-stranded breaks production in apurinic DNA is discussed.
