 74-124 1.37e-27

C-terminal zinc ribbon domain of RPB9 subunit of RNA polymerase II; The C-terminal zinc ribbon domain (C-ribbon) of subunit B9 (Zn-ribbon_RPB9) in RNA polymerase (Pol) II is involved in intrinsic transcript cleavage. Eukaryote genomes are transcribed by three nuclear RNA polymerases (Pol I, II and III) that share some subunits. RPB9 have strong homology to RPA12 of Pol I and RPC11 of Pol III subunits but its intrinsic cleavage activity is weaker for Pol II. Zn-ribbon_RPB9 is homologous to Pol II elongation factor TFIIS domain III. The very weak cleavage activity of Pol II is stimulated by TFIIS. RPB9 has two zinc-binding domains separated by a flexible linker.

C-terminal zinc ribbon domain of RNA polymerase intrinsic transcript cleavage subunit; The homologous C-terminal zinc ribbon domains of subunits A12.2, Rpb9, and C11 in RNA Polymerases (Pol) I, II, and III, respectively are required for intrinsic transcript cleavage. TFS is a related archaeal protein that is involved in RNA cleavage by archaeal polymerase. These proteins have two zinc-binding beta-ribbon domains, N-terminal zinc ribbon (N-ribbon) and C-terminal zinc ribbon (C-ribbon). Transcription Factor IIS (TFIIS) domain III is homologous to the C-ribbon domain that stimulates the weak cleavage activity of Rpb9 for Pol II.

 77-125 2.59e-03

C-terminal zinc ribbon domain of archaeal Transcription Factor S (TFS); TFS is an archaeal protein that stimulates the intrinsic cleavage activity of archaeal RNA polymerase. TFS C-terminal domain shows sequence similarity to the homologous C-terminal zinc ribbon domain of subunits A12.2, Rpb9, and C11 in eukaryotic RNA Polymerases (Pol) I, II, and III, respectively and domain III of TFIIS. TFS is not a subunit of archaeal RNA polymerase even though its domains arrangement is similar to A12.2, Rpb9, and C1. TFS is a transcription factor with a similar function to eukaryotic TFIIS. TFS has external cleavage induction activity and improves the fidelity of transcription. TFS has two zinc-binding domains.
