The yeast ISWI complexes have distinct nucleosome spacing activities. (A) Components required for the assembly of regularly spaced nucleosome arrays using the yeast ISWI complexes. Presence (+) and absence (−), respectively, of the components are indicated. Partial and extended MNase digestions were taken for each sample. (B) Titration of the yeast ISWI complexes in nucleosome spacing assay. Threefold serial dilution of the yeast ISWI complexes was used. All reactions contained NAP1, core histones, λ DNA, and ATP at standard concentrations. Partial and extended MNase digestions were performed for each sample.
