XPA (xeroderma pigmentosum group A) protein is an essential factor for NER (nucleotide excision repair) which is believed to be involved in DNA damage recognition/verification, NER factor recruiting and stabilization of repair intermediates. Past studies on the structure of XPA have focused primarily on XPA interaction with damaged DNA. However, how XPA(More)
A restriction endonuclease cleavage map of bacteriophage T3 DNA has been constructed. The enzymes used and, within parentheses, the number of their cleavage sites on T3 DNA are: HindIII (1), XbaI (1), BglII (1), KpnI (2), MboI (9), and HpaI (17). The size and the relative location of each fragment have been established, defining an accurate physical map of(More)
