[Acid-soluble, non-histone proteins in rat liver chromatin. Interaction with DNA].
Some properties of nonhistone proteins of rat liver chromatin (Mr 40 +/- 1 and 41 +/- 1 KD) are described. These proteins are abundant in monomeric particles formed at the early steps of chromatin fragmentation by Ca2+,Mg2+-DNase. The proteins are not extracted from chromatin by 5% HClO4 and 1 M NaCl, but can be extracted by 0.4 n H2SO4 and 2 M NaCl. Study on proteins binding to DNA demonstrated that in 0.05 M NaCl these proteins are bound both to bovine satellite DNA and to the plasmid pBR 322 DNA.
