The Non-catalytic Function of XPG Protein during Dual Incision in Human Nucleotide Excision Repair
1 Jun 1997
Abstract excerpt
XPG is a member of the FEN-1 structure-specific endonuclease family. It has 3'-junction cutting activity on bubble substrates and makes the 3'-incision in the human dual incision (excision nuclease) repair system. To investigate the precise role of XPG in nucleotide excision repair, we mutagenized two amino acid residues thought to be involved in DNA binding and catalysis, overproduced the mutant proteins using a...
