This domain belongs to human mitochondrial DNA polymerase (Pol-gamma). Pol-gamma has a catalytic subunit, Pol gamma-A, which possesses both polymerase and proofreading exonuclease activities and an accessory subunit, Pol gamma-B, which accelerates polymerization rate and suppresses exonuclease activity. This domain is the exonuclease domain of the catalytic subunit, Pol gamma-A [1].	Domain
B, C	PF03129	Anticodon binding domain (HGTP_anticodon)	Anticodon binding domain	This domain is found in histidyl, glycyl, threonyl and prolyl tRNA synthetases [1] it is probably the anticodon binding domain [2].	Domain
