Lysyl-tRNA synthetase has been isolated from E. coli. The enzymatic activity elutes as three or four bands from a hydroxyl-apatite column. Polyacrylamide gel analysis shows that each of these bands contain more than one enzymatically active protein species. The molecular weights of the subunits of these species provides an explanation for the variation in the molecular weights previously reported for this enzyme.
赖氨酰 - tRNA合成酶已从大肠杆菌中分离出来。其酶活性从羟基磷灰石柱上洗脱下来时呈现为三条或四条带。聚丙烯酰胺凝胶分析表明，这些条带中的每一条都包含不止一种具有酶活性的蛋白质种类。这些种类的亚基分子量为先前报道的该酶分子量变化提供了解释。
