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 ...

Preparative affinity precipitation of L-lactate dehydrogenase
Journal of Biotechnology, 1989Abstract The methoxylated p-sulphonate isomer of the triazine dye C.I. Reactive Blue 2, selectively precipitates L-lactate dehydrogenase from crude rabbit muscle extracts. At mildly alkaline pH values and a 7-fold molar excess of the dye analogue to enzyme subunits, 106 mg of homogeneous lactate dehydrogenase essentially free of soluble ligands and ...

Mechanism of allosteric transition of bacterial L-lactate dehydrogenase
Faraday Discussions, 1992The allosteric behaviour of L-lactate dehydrogenase (L-lactate:NAD+oxidoreductase, EC 1.1.1.27, LDH) from Bifidobacterium longum aM101-2 was studied by means of the subunit hybridization technique as well as X-ray crystallography. Homotropic allosteric response of the LDH activity was found against the concentration of its substrate, pyruvate ...

Molecular Basis of Allosteric Activation of Bacterial L-Lactate Dehydrogenase
Journal of Molecular Biology, 1993The three-dimensional structure of allosteric L-lactate dehydrogenase from Bifidobacterium longum, the first example of a T-state structure of L-lactate dehydrogenase, has been determined to 2.0 A. A comparative study of this structure with the previously reported R-state structure from Bacillus stearothermophilus has revealed the allosteric activation

Analytica Chimica Acta, 1996
Carbon-based thick-film electrodes employing nicotinamide adenine dinucleotide (NAD+)-dependent dehydrogenases were constructed by screen printing. Cyclic voltammetric and amperometric investigations of the thick-film electrode showed significantly different electrocatalytic properties toward NADH compared to conventional polished electrodes ...

Relationship between L-lactate dehydrogenase and multidrug resistance in Staphylococcus xylosus
Archives of Microbiology, 2021Staphylococcus xylosus is a gram-positive bacterium that has attracted much attention due to its increasing clinical appearance, frequently associated with serious multidrug resistance cases. L-lactate dehydrogenase (LDH) has been related to drug resistance in several bacterial species. However, the mechanism of multidrug resistance in S.
