Purification and crystallization of components of the protein-synthesizing system from Thermus thermophilus
1991
Abstract An extreme thermophilic bacterium Thermus thermophilus has been chosen as a source for the isolation of components of the protein-synthesizing system to investigate their structures by X-ray crystallographic methods. The scheme of simultaneous isolation of ribosomes, tRNA, three elongation factors, several aminoacyl-tRNA synthetases and several enzymes has been developed. Methods of purification of ribosomes and individual ribosomal proteins without denaturation were elaborated. Crystals of the elongation factor G , the 70S ribosome, the 30S ribosomal subunit, six ribosomal proteins and three aminoacyl-tRNA synthetases have been obtained. Structural investigations of EF-G and the 70S ribosome are underway.
