title: Isolation of histone-like proteins from mitochondria of bovine heart.
abstract: Two methods for isolating and purifying histone-like proteins from mitochondria of bovine heart are described. In the first, a sonicated extract of the mitochondria was fractionated in three chromatography steps, including affinity chromatography on DNA-cellulose, to purify a protein that resembles very closely the histone-like protein (HM) of yeast mitochondria. In the second method, an acid extract of the heart mitochondria was the starting material; two other histone-like proteins were separated. Thus, as in mitochondria of Xenopus laevis, several histone-like proteins are present in mitochondria of bovine heart.
