Localization of l-lactate dehydrogenase in mitochondria
Archives of Biochemistry and Biophysics, 1986Relatively small but persistent amounts of L-lactate dehydrogenase (LDH) activity were found in mitochondrial preparations isolated from liver of the rat. Using a variety of cytosolic markers, it was found that essentially no cytosolic contamination was present. Respiratory velocities and respiratory control with L-lactate were somewhat lower than with

Electron microscopic observations of l-lactate dehydrogenase crystals
Journal of Ultrastructure Research, 1969Thin sections and shadowed replicas of dogfish muscle lactate dehydrogenase crystals were examined in the electron microscope. The observed periodicities are in good agreement with the X-ray data. The density variations in the stained thin sections can be explained using the X-ray determined molecular structure.

L(+)‐lactate dehydrogenases from Hymenolepis diminuta (Cestoda)
Journal of Experimental Zoology, 1973AbstractProperties of L( + )‐lactate dehydrogenases from infective eggs, cysticercoids, immature proglottids (anteriors), and pre‐patent (seven day) infections of H. diminuta were studied. Fractionation of isozymes by disc gel and cellulose acetate electrophoresis was unsatisfactory, but some fractionation was obtained by electrofocusing.

Low resolution study of crystalline l-lactate dehydrogenase
Journal of Molecular Biology, 1969The electron density distribution of dogfish muscle lactate dehydrogenase, based on 2000 independent terms extending to 5 A resolution, shows the shape of the tetrameric molecule and of the individual subunits. Each of the five heavy-atom derivatives used in the calculation substitutes at one or more of three sites A, B and C. The heavy-atom compounds (

D- and L-lactate dehydrogenases in Escherichia coli
Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966Summary (1) The oxidation of DL -lactate by Escherichia coli NCTC 8196 has been shown to be catalysed by two enzymes, one specific for D -lactate, the other specific for L -lactate. (2) Both enzymes were present during aerobic and anaerobic growth on all media tested.

D-form lactate is often found in fermented foods and excessive dietary intake of D-lactate may cause metabolic stress in both infants and patients. Leuconostoc citreum is a major lactic acid bacterium that produces D-lactate in fermented foods. The aim of this study was to change the pyruvate carbon flux in L.

Negative entropy production in L-lactate dehydrogenase kinetics
Archive of Biochemistry, 2023Fröhlich theory of coherent excitations in biological systems is analyzed. L-lactate dehydrogenase kinetics is studied using the activation process model for non-equilibrium cases. The model explains the process of energy accumulation necessary for carrying out catalytic reactions in a living cell by means of interaction of quantum subsystems with ...
