Using purified chromatin rings, what defines a promoter is now explored. Exposure of purified templates to the RSC ATP-dependent remodeling complex leads to Translocation of promoter rather than open reading frame nucleosomes. Together with analysis of the effect of histone deacetylase on this process, this argues that nucleosomes define promoter-specificity.
