Descrizione generale
Research area: Cell Signalling D-lactate dehydrogenase belongs to the D-isomer-specific 2-hydroxyacid dehydrogenase family. Lactate dehydrogenase (LD) is a tetramer consisting of two (H and M) subunits. It has five isozymes (LD1 to LD5) and this composition varies in different tissues. LD1 is abundant in the kidney, heart, and erythrocytes. LD5 is found in the liver and skeletal muscles. LD is a ubiquitous molecule found in plants, yeast, mammals, and microorganisms and is a member of the oxidoreductase family.
Azioni biochim/fisiol
Lactic dehydrogenase (LDH)plays an important role in the glycolytic pathway where it converts pyruvate tolactate by using NAD+ as a co-factor. It is considered animportant molecule that can be used in cancer therapy as it acts as aglycolytic inhibitor. Inhibition of LDH is associated with blocking of aerobicglycolysis in tumour cells.
Definizione di unità

The gene encoding D-lactate dehydrogenase (D-lactate: NAD+ oxidoreductase, EC 1.1.1.28) of Lactobacillus plantarum has been sequenced, and expressed in Escherichia coli cells with an inducible expression plasmid, in which the 5'-noncoding region of the gene was replaced with the tac

D-lactic acid in the mammalian body is mainly of microbiological origin and is often located somewhere along the digestive tract. Surgical, extensive re-sectioning of the small bowel may be one of the risk factors for altered balance in the microbiological

A challenge model was used to evaluate a new approach to controlling acute acidosis. Acute acidosis reduces performance in both dairy and beef cattle and most often occurs as a consequence of ingestion of large amounts of readily fermentable starch

NAD-dependent l- and d-lactate dehydrogenases coexist in Lactobacillus genomes and may convert pyruvic acid into l-lactic acid and d-lactic acid, respectively. Our findings suggest that the relative catalytic efficiencies of ldhL- and ldhD-encoded products are crucial for the optical purity

We proposed the first application of an electrophoretically mediated microanalysis (EMMA) method for fast online discrimination and determination of substrate enantiomers, which was achieved by just one EMMA assay. Lactate dehydrogenase (LDH)-catalyzed reaction was studied to evaluate the feasibility and
