4YM5, 4YM6 - PubMed Abstract: 
UV-DDB, an initiation factor for the nucleotide excision repair pathway, recognizes 6-4PP lesions through a base flipping mechanism. As genomic DNA is almost entirely accommodated within nucleosomes, the flipping of the 6-4PP bases is supposed to be extremely difficult if the lesion occurs in a nucleosome, especially on the strand directly contacting the histone surface ...
