[Similarity of non-histone proteins of chromatin from the differentiation zone of pea root and stem. Lack of pronounced organ specificity].
The properties of individual fractions of non-histone proteins of chromatin from the differentiation zone of pea root and stem were compared. The total preparation of non-histone proteins were fractionated by a step-wise elution of NaCl on DEAE-cellulose. Their amino acid content and N-terminal groups were determined. The electrophoretic mobility of the protein zones were studied, using polyacrylamide gel electrophoresis in the presence of Na-SDS. Similar chromatographical fractions of hon-histone proteins from the differentiation zone of pea root and stem had a similar amino acid composition and electrophoretic mobility of the protein zones and identical N-terminal groups. The data obtained suggest that the nonhistone proteins of chromatin from different tissues contain a relatively small amount of proteins with a very similar or identical primary structure and that their diversity in a number of studies is due to their phosphorylation, acetylation and amidation.
