Abstract

In yeast, Rad7 and Rad16 are two proteins required for nucleotide excision repair (NER) of non-transcribed chromatin. They have roles in damage recognition, in the postincision steps of NER, and in ultraviolet-light-dependent histone H3 acetylation. Moreover, Rad16 is an ATP-ase of the SNF2 superfamily and therefore might facilitate chromatin repair by nucleosome remodelling. Here, we used yeast rad7Delta rad16Delta mutants and show that Rad7-Rad16 is also required for NER of UV-lesions in three functionally distinct nucleosome-free regions (NFRs), the promoter and 3'-end of the URA3 gene and the ARS1 origin of replication. Moreover, rapid repair of UV-lesions by photolyase confirmed that nucleosomes were absent and that neither UV-damage formation nor rad7Delta rad16Delta mutations altered chromatin accessibility in NFRs. The data are consistent with a role of Rad7-Rad16 in damage recognition and processing in absence of nucleosomes. An additional role in nucleosome remodelling is discussed.
