Structural highlights
FunctionDP2L_PYRHO Possesses two activities: a DNA synthesis (polymerase) and an exonucleolytic activity that degrades single-stranded DNA in the 3'- to 5'-direction. Has a template-primer preference which is characteristic of a replicative DNA polymerase (By similarity). Publication Abstract from PubMedArchaea-specific D-family DNA polymerase forms a heterotetramer consisting of two large polymerase subunits and two small exonuclease subunits. The N-terminal (1-300) domain structure of the large subunit was determined by X-ray crystallography, although approximately 50 N-terminal residues were disordered. The determined structure consists of nine alpha helices and three beta strands. We also identified the DNA-binding ability of the domain by SPR measurement. The N-terminal (1-100) region plays crucial roles in the folding of the large subunit dimer by connecting the approximately 50 N-terminal residues with their own catalytic region (792-1163).
