title: [Isolation and properties of malate dehydrogenase from meso- and thermophilic bacteria].
abstract: A scheme of purification of malate dehydrogenase from Macromonas bipunctata strain D-405 and Vulcanithermus medioatlanticus DSM 14978T was developed. This scheme was used to obtain electrophoretically homogeneous enzyme preparations of the mesophilic bacterium M. bipunctata (specific activity, 26.9 +/- 0.8 U/mg protein; yield, 10.9%) and the thermophilic bacterium V. medioatlanticus (specific activity, 5.0 +/- 0.2 U/mg protein; yield, 19.2%). Using these high-purity enzymatic preparations, the physicochemical and regulatory properties of malate dehydrogenase were studied and the differences in kinetic characteristics and thermal stability of the preparations were determined.
