    6289   Nucleotide Excision Repair  A DNA Repair Process in Which a Small Region of the Strand Surrounding the Damage Is Removed From the DNA Helix As an Oligonucleotide. the Small Gap Left in the DNA Helix Is Filled in by the Sequential Action of DNA Polymerase and DNA Ligase. Nucleotide Excision Repair Recognizes a Wide Range of Substrates Including Damage Caused by Uv Irradiation (pyrimidine Dimers and 6 4 Photoproducts) and Chemicals (intrastrand Cross Links and Bulky Adducts). 
    4003   ATP Dependent DNA Helicase Activity  Catalysis of the Reaction: ATP + H2o = Adp + Phosphate; This Reaction Drives the Unwinding of the DNA Helix.
