Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF01702 TGT Queuine tRNA-ribosyltransferase Family
A PF01472 PUA PUA domain Family
A PF14810 TGT_C2 Patch-forming domain C2 of tRNA-guanine transglycosylase Domain Domain C2 of tRNA-guanine transglycosylase is formed by a four-stranded anti-parallel beta-sheet lined with two alpha helices. It has conserved basic residues on the surface of the beta-sheets as does the C-terminal domain PUA, Pfam:PF01472. The catalytic domain, TGT has conserved basic residues on the outer surface of the N-terminal three-stranded beta sheet, which closes the barrel, and it is postulated that these basic residues from the three domains form a continuous, positively charged patch to which the tRNA binds [1]. PFAM PF14810
A PF14809 TGT_C1 C1 domain of tRNA-guanine transglycosylase dimerisation Domain This short region of the tRNA-guanine transglycosylase enzyme acts as the dimerisation domain of the whole protein [1]. PFAM PF14809
