Abstract

Histone interactions which occur, at moderate ionic strengths, when several types of purified, renatured histones are mixed at equimolar ratios have been studied. The four histones H₂A, H₂B, H₃ and H₄ complex and form dimers. Histone H¹ does not interact with the other four histone types and does not form dimers. Mixing of single histone species with preformed histone pairs as well as mixing of two different types of histone pairs, leads to exchange of histones among the pairs and formation of dimers. No trimers are formed. The dimers are in equilibrium with high-molecular weight histone structures.
