A high degree of correlation between the capability of subclasses of human immunoglobulins G to form aggregates due to thermal treatment, and their complement-binding activity was established. On the basis of the experimental data obtained by the methods of light scattering, circular dichroism, microcalorimetry, it was supposed that "hinge" region of(More)
Isolation and purification of "malic-enzyme" NADP was done using fractionation by ammonium sulfate, anion-exchange chromatography on DEAE cellulose, gel-filtration through Sephadex G-200 and purification on DEAE Sephadex A-50. The isoenzyme isolated had a specific activity of 40-50 mkM/mg protein per min (approximately 80-fold purification) and contained(More)
Kinetic properties of purified chloroplast isoenzyme of the "malic" enzyme from corn leaves were studied. The enzyme had optimum activity at pH 8.0 and 36 degrees C. Under standart conditions the Michaelis constants for the "malic" enzyme with Mn2+ as cofactor are 0.091 mM for malate and 0.04 mM for NADP. In case of Mg2+ as cofactor they are 0.66 and 0.02(More)
The activities of NADP-dependent malate dehydrogenases in greening etiolated maize leaves were studied. "Malic" enzyme (EC 1.1.1.40) in bundle sheath cells developed slower as compared to NADP-malate dehydrogenase synthesizing malic acid in mesophyll chloroplasts. The increase in "malic" enzyme activity in the light was suppressed by protein synthesis(More)
