[Isolation, various physico-chemical and catalytic properties of L-methionine-gamma-lyase from Pseudomonas taetrolens].

Homogeneous preparation of L-methionine gamma-lyase was isolated from Ps. taetrolens. As shown by gel filtration and gradient polyacrylamide gel electrophoresis molecular mass of the native L-methionine gamma-lyase was 130-135 kDa.

[Characteristics of lipid composition, lipid peroxidation intensity and ATPase activity of lymphocytes in children with acute respiratory viral infections].

Content of total lipids, intensity of lipid peroxidation and activity of ATPases were studied in lymphocytes of children with acute respiratory-viral infection (ARVI). Decrease in the content of total lipids correlated with lipid peroxidation in ARVI. At the same time, a decrease in the activity of ATPases occurred due to a decrease in the content of total lipids and alteration in the phospholipid composition of lymphocyte membranes.
