The ability of Saccharomyces cerevisiae transcription factors IIIC and IIIB to bend DNA at their binding sites in a tRNA(Gln) gene has been analyzed by two methods that are based on the anomalous electrophoretic mobility of bent DNA in a tight gel network. Both transcription factors bend DNA, TFIIIB more than TFIIIC. The effective centers of the transcription factor IIIB- and IIIC-induced bends are not in helical phase.
