NMR SOLUTION STRUCTURE OF THE N-TERMINAL DOMAIN OF DNA POLYMERASE BETA, 55 STRUCTURES

Released:

Function and Biology Details

Reactions catalysed:
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1)
The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate
Biological process:
