Abstract
The amount of different histone fractions (resolved on CMC Column), their amino acid composition, and the composition of nonhistone chromatin protein fractions from tobacco stem callus tissue were determined. The amounts of F I, F II and F III histones were found to be 92%, 5% and 3% respectively. Non-histone protein fractions P 1 (part of chromatin insoluble in 1 M NaCl) and P 4 (fraction eluting from the CMC Column by 0.175 M NaCl) and the lysine-rich histone fraction F I were found to contain 3%, 2.1% and 0.5% hydroxyproline respectively. It is suggested that proline hydroxylation of histones may play a role similar to acetylation, methylation, or phosphorylation of histones.
