Crystal Structure of hogg1 D268E Mutant with Base-Excised DNA and 8-aminoguanine

Released:
Source organism: Homo sapiens

Function and Biology Details

Reaction catalysed:
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
