A method for isolating tyrosyl-tRNA synthetase from Thermus thermophilus is described, including ammonium sulfate fractionation, chromatography on DEAE-sepharose, hydroxyapatite, heparin-sepharose and hydrophobic chromatography on Toyopearl HW-65. The yield of the purified enzyme was 1.6 mg per 1 kg of T. thermophilus cells. The enzyme is a dimer protein of the alpha 2 type with molecular weight of 100 kDa.

The entrapping of a plague capsular antigen into the liposomes, prepared by the "reverse phase" evaporating method, was investigated. Both the native antigen and the antigen modified by palmitoylchloride were used. The entrapping of the modified antigen into the liposomes was greater than that of the native one: 46.1 +/- 5.4% and 3.7 +/- 2.7%, respectively. The highest content of the antigen on the membrane surface was observed when using palmitoylized protein and liposomes with egg lecithin, cholesterol and dicethylphosphate in the molar ratio 7:2:1.
