General description

Cytoplasmic Isozyme

Application

Malic dehydrogenase has been used in a study to assess the use of a long-wavelength homogeneous enzyme immunoassay for the determination of amikacin in water samples. It has also been used in a study to investigate the lipid metabolism in a liver exposed to cadmium.

Biochem/physiol Actions

The surfactant cetyl (hexadecyl) trimethylammonium bromide inhibits the cytoplasmic isoform of porcine heart malate dehydrogenase but has no effect on the mitochondrial form. SDS however; inhibits both isoforms.

Unit Definition

One unit will convert 1.0 μmole of oxalacetate and β-NADH to L-malate and β-NAD per min at pH 7.5 at 25 °C.

Physical form

Suspension in 3.2 M (NH4)2SO4, 0.1 M KH2PO4, pH 7.0
