The TGS domain is named after ThrRS, GTPase, and SpoT [1]. Interestingly, TGS domain was detected also at the amino terminus of the uridine kinase from the spirochaete Treponema pallidum (but not any other organism, including the related spirochaete Borrelia burgdorferi). TGS is a small domain that consists of ~50 amino acid residues and is predicted to possess a predominantly beta-sheet structure. There is no direct information on the functions of the TGS domain, but its presence in two types of regulatory proteins (the GTPases and guanosine polyphosphate phosphohydrolases/synthetases) suggests a ligand (most likely nucleotide)-binding, regulatory role [1].
This domain is part of the G domain found at the C-terminus of Pfam:PF01926 in archaeal and eukaryotic GTP-binding proteins. Members of this entry form a subfamily within the Obg family of GTPases and includes YGR210 from yeasts and its homologues fr ...
This domain is part of the G domain found at the C-terminus of Pfam:PF01926 in archaeal and eukaryotic GTP-binding proteins. Members of this entry form a subfamily within the Obg family of GTPases and includes YGR210 from yeasts and its homologues from archaea [1]. This domain seems to be necessary for the complete activity of the protein for binding of both adenine and guanine nucleotides, with a preference for guanine nucleotides. This domain contains the NKxD motif, known as the G4 motif [1].
