The domain within your query sequence starts at position 167 and ends at position 283; the E-value for the Thg1C domain shown below is 2.6e-47.



PFAM accession number:PF14413
Interpro abstract (IPR025845):

Thg1 was originally characterised as synthesising the guanine nucleotide at the -1 position of the histidinyl tRNA (HtRNA). Thg1 has also been shown to have polymerase activity, which has been proposed to be the ancestral activity of this enzyme [(PUBMED:20080734), (PUBMED:16731615)].

Thg1 polymerases contain an additional region of conservation C-terminal to the core palm domain that comprise of 5 helices and two strands [(PUBMED:20591188)]. This region has several well-conserved charged residues including a basic residue found towards the end of the first helix of this unit might contribute to the Thg1-specific active site [(PUBMED:20591188)]. This C-terminal module of Thg1 is predicted to form a helical bundle that functions equivalently to the fingers of the other nucleic acid polymerases, probably in interacting with the template HtRNA [(PUBMED:20591188)].
