General description

LDH (lactic dehydrogenase), a glycolytic enzyme, particularly present in skeletal muscle, heart, liver, kidneys, brain, lungs and red blood cells. It has five isoenzyme forms. LDH possess a tetrameric structure.

Application

Lactic Dehydrogenase, recombinant from E. coli has been used:
  • in lactate dehydrogenase (LDH) and malate dehydrogenase 1 (MDH1)assays and cross-linking assays[1]
  • to prepare assay buffer to measure pyruvate kinase (PYK) by coupled assay
  • in in vitro DltC D-alanylation assay

Biochem/physiol Actions

L-lactic dehydrogenase catalyzes the conversion of L-lactate into L-pyruvate while reducing NAD+ to NADH and H+.
Conversion of L-lactate into L-pyruvate is crucial in hypoxic and anaerobic conditions, especially when synthesis of adenosine triphosphate (ATP) by oxidative phosphorylation is interrupted.

Other Notes

1 U entspricht der Enzymmenge, die 1μmol Pyruvat pro Minute bei pH 7.4 und 25°C (NADH als Cofaktor) reduziert.

Questions

1–4 of 4 Questions  
  1. Does this enzyme catalyze the reaction of L-lactate to L-pyruvate, with NAD+ -> NADH as cofactors, or does it catalyze the conventional L-pyruvate to L-lactate with NADH -> NAD+?

    1 answer
    1. This enzyme catalyzes the conversion of L-lactate into L-pyruvate while reducing NAD+ to NADH and H+.

      Helpful?

  2. Can you provide more information on the biological source for recombinant LDH 59747? Does the certificate of origin specify whether the recombinant protein is from mice or another source? It seems that the certificate of origin does not offer detailed information to clarify this.

    1 answer
    1. The material is Lactate dehydrogenase from chicken heart, expressed in recombinant microbes.

      Helpful?

  3. I want to know the molecular weight of this protein

    1 answer
    1. This product is a recombinant enzyme from E. coli. The species and tissue of origin is the chicken heart. The molecular weight of this material has not been determined. However, according to Huston et al. 1972, Lactate Dehydrogenase from the bovine heart has a molecular weight of approximately 136,700 daltons.

      Helpful?

  4. What species is Product No. 59747, Lactic Dehydrogenase, recombinant from E. coli?

    1 answer
    1. This product is a recombinant Lactic Dehydrogenase from chicken heart made in E. coli.
