[Characteristic features of heat inactivation of leucyl-tRNA- synthetase from the rabbit liver in the presence of various tRNA conformers].

The effect of biologically inactive and active tRNA conformers on heat inactivation of leucyl-tRNA synthetase was investigated. The data presented show that inactive tRNA conformers seem to form complexes with leucyl-tRNA synthetase, but the thermal stability of the enzyme involved in the complex with inactive and active tRNA conformers is rather different.
