Abstract
We amplified the coding regions of the previously cloned HI genes HI-I , HI degrees and HIt and inserted them into the expression vector pET- IId. The synthesis of the HI histones can be induced in the appropriat e strains of bacteria, and the HI histones can be readily purified. We report detailed protocols for the purification of the expressed prote ins using combinations of ion-exchange and reverse-phase HPLC. Suffici ent amounts of each pure variant protein can be obtained for use in ph ysical studies of HI-DNA interactions.
