Oligonucleotide structural parameters that influence binding of 5'-O-triphosphoadenylyl-(2' .fwdarw. 5')-adenylyl-(2' .fwdarw. 5')-adenosine to the 5'-O-triphosphoadenylyl-(2' .fwdarw. 5')-adenylyl-(2' .fwdarw. 5')-adenosine dependent endoribonuclease: chain length, phosphorylation state, and heterocyclic base

higher core oligomers but approximately 100 times more effectively than the trimer core, A2'p5'A2'p5'A. (4) Base-modified analogues, such as p5'C2'p5'C2'p5'C, p5'U2'p5'U2'p5'U, or p5'I2'p5'I2'p5'I, were at least 2000 times less effectively bound to the endonuclease than p5'A2'p5'A2'p5'A. (5) The triphosphate ppp5 'I2'p5'I2'p5'I was 10 000 times less active than 2-5A as an inhibitor of translation. These
