[Study of the substrate specificity of T4 RNA ligase: interaction of the enzyme with ATP analogs modified through the ribose residue and with affinity sorbents].
To elucidate the role of the ribose moiety in substrate binding, various ATP derivatives modified in ribose moiety were studied as probes for the T4 RNA ligase first stage reaction. The kinetic… Expand
[Substrate specificity of T4 RNA-ligase: the role of a purine nucleotide base in forming a covalent AMP-RNA-ligase complex].
The NTP binding site of bacteriophage T4 RNA-ligase (EC 126.96.36.199) was studied using several ATP analogs modified in the purine moiety of the nucleotide at positions 1, 2, 6 and 8: adenosine-N'-oxide… Expand
