Transcription initiation by RNA polymerase II does not require hydrolysis of the beta-gamma phosphoanhydride bond of ATP.

When transcription by RNA polymerase II from the major-late (ML) promoter was studied with purified basal transcription factors, it was observed that transcription from negatively-supercoiled ML templates did not require transcription factor IIH (TFIIH). Addition of the basal factor TFIIE was highly stimulatory, but not absolutely required for this reaction. In contrast, transcription from relaxed or linear ML templates required both TFIIE and TFIIH. Adenylylimidodiphosphate (AMP-PNP), an ATP analog with a non-hydrolyzable beta-gamma phosphoanhydride bond, could support RNA synthesis from supercoiled templates, but not from linear templates. Since AMP-PNP cannot act as a cofactor for the DNA helicase activity of TFIIH, this finding independently supported the conclusion that TFIIH is not required for transcription of negatively-supercoiled templates. Taken together, these data indicate that the ATP-dependent step in transcription initiation by RNA polymerase II is caused by a requirement for the ATP-dependent helicase activity of the basal factor TFIIH. The experiments also show that transcription initiation by RNA polymerase II does not require hydrolysis of the beta-gamma phosphoanhydride bond of ATP per se.

General transcription factors are required for accurate initiation of transcription by RNA polymerase II. Human cDNAs encoding subunits of these factors have been cloned and sequenced. Using fluorescence in situ hybridization (FISH), we show here that the genes encoding the TATA-box binding protein (TBP), TFIIB, TFIIE alpha, TFIIE beta, RAP30, RAP74 and the 62 kDa subunit, of TFIIH are located at the human chromosomal bands 6q26-27, 1p21-22, 3q21-24, 8p12, 13q14, 19p13.3 and 11p14-15.1, respectively. This dispersed localization of a group of functionally related gene provides insights into the molecular mechanism of human genome evolution and their possible involvement in human diseases.
