Identification of the region in histone H2B targeted by the HMG-14 7C point mutant. A proteolytic digest of the 125I-labeled histone was fractionated by HPLC (A) and the peptides present in the fractions were analyzed by PAGE. The targeted peptides were identified by autoradiography (B) of Coomassie blue-stained gels (C).
