Characterization of sequence variability in nucleosome core histone folds.

Abstract excerpt

The three-helix, approximately 65-residue histone fold domain is the most structurally conserved part of the core histones H2A, H2B, H3, and H4. However, it evinces a notable degree of sequence variation within and between histone classes. We used two approaches to characterize sequence variation in these histone folds, toward elucidating their structure/function relationships and evolution. On the one hand we...
