Abstract
A set of differently spin labeled (dT)c is used to evaluate thymidine dynamics and some of the structural features in a (dT) n-gene 5 protein complex. ESR evidence is presented that only one of the four thymidine residues bound in the DNA binding channel shows strong immobilization, whereas the other three display significant mobility of the order of nanoseconds. It is hypothesized that the accessability of such mobile bases could be critical to the recognition of the (dT)n-gene 5 protein complex in auxiliary interactions with other proteins and competitive DNAs.This publication has 11 references indexed in Scilit:
