title: [Isolation and purification of histone-specific acetyltransferases from the rat liver].
abstract: There forms of histone-specific acetyltransferases--A, B and C are obtained from the rat liver nuclei. The isolation process included nuclei generation, ammonium sulphate salting-out of proteins, DEAE-cellulose, hydroxyl-apatite, phosphocellulose chromatography and Sephadex C-200 gel-filtration. Acetyltransferases A, B and C from the nuclei were purified 56.8, 144.1 and 42.3 times, respectively. Histones were preferential substrates of the obtained enzymes. Molecular mass of acetyltransferases was determined by Sephadex G-150 and G-200 gel-filtration. It was 120 for enzyme A, about 90 for B and above 200 kDa for C.
