The YqgF domain of SPT6 proteins is homologous to the E.coli RuvC [1] but its putative catalytic site lacks the carboxylate side chains critical for coordinating magnesium ions that mediate phosphodiester bond-cleavage [2]
This domain is found in Tex protein and other related proteins. Tex belongs to a family of prokaryotic transcriptional accessory factors that likely function in a variety of transcriptional processes [1-5].This domain is mainly helical, consisting of ...
This domain is found in Tex protein and other related proteins. Tex belongs to a family of prokaryotic transcriptional accessory factors that likely function in a variety of transcriptional processes [1-5].This domain is mainly helical, consisting of a number of small helices that wrap around a long central helix.
SHS2 domain found in N terminus of Rpb7p/Rpc25p/MJ0397
Rpb7 bind to Rpb4 to form a heterodimer. This complex is thought to interact with the nascent RNA strand during RNA polymerase II elongation[1]. This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at leas ...
Rpb7 bind to Rpb4 to form a heterodimer. This complex is thought to interact with the nascent RNA strand during RNA polymerase II elongation[1]. This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at least one of the subunits contacted by the transcription factor TIF-IA [2]. The N terminus of Rpb7p/Rpc25p/MJ0397 has a SHS2 domain that is involved in protein-protein interaction [3].
The S1 domain occurs in a wide range of RNA associated proteins. It is structurally similar to cold shock protein which binds nucleic acids. The S1 domain has an OB-fold structure.
