PF14639 | Holliday-junction resolvase-like of SPT6 (YqgF) | Holliday-junction resolvase-like of SPT6 | 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] | Domain | |
PF14641 | Helix-turn-helix DNA-binding domain of SPT6 (HTH_44) | Helix-turn-helix DNA-binding domain of SPT6 | This helix-turn-helix represents the first of two DNA-binding domains on the SPT6 proteins. | Domain | |
PF22706 | Tex central region-like (Tex_central_region) | Tex central region-like | 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 ... | Domain | |
PF21710 | Spt6, S1/OB domain (Spt6_S1) | Spt6, S1/OB domain | This entry represents the S1/OB-fold domain of Spt6. This domain has structural similarity to S1 domain but lacks the typical S1 binding cleft residues involved in nucleic acid binding [1], therefore, this domain in Spt6 may be involved in interacti ... | Domain | |
