The method of purification of leucyl-tRNA-synthetase (LeuRS) from rabbit liver and pig myocardium is described. Two forms (EMsub>1 and E2) of LeuRS are distinguished by hydro-xylapatite chromatography of partially purified enzyme from pig myocardium. The molecular mass was calculated to be 185000 for LeuRS from rabbit liver and 158000 for EMsub>1 from pig myocardium. E2 is stated to contain aminoacyl-tRNA synthetase activities of other amino acid specificities and is a complex of enzymes with molecular mass of about 800000.
