It has been shown that tRNA-Sepharose, a chromatographic adsorbent containing unfractionated tRNA bound to a Sepharose matrix, is a useful, group-specific adsorbent for fractionation of the plant aminoacyl-tRNA synthetases. Conditions are described in which Val-, Trp-, Phe-, Leu- and Ile-tRNA synthetases from yellow lupin seeds can be separated from each other on the tRNA-Sepharose columns. Factors affecting affinity chromatography on the tRNA-Sepharose columns are discussed. The affinity chromatography procedure for the purification of lupin Ser-tRNA synthetase to homogenity is described.
