生物活性/药理作用

Also catalyzes the oxidation of other L-2-hydroxymonocarboxylic acids.

Lactic Dehydrogenase (LDH) has a total molecular weight of 140 kDa and is composed of 4 subunits which are designated M subunit (muscle) and H subunit (heart).These subunits may be mixed in any of 5 combinations (M4, M3H1, M2H2, MH3, and H4).Skeletal muscle contains LDH that is predominately M4 with some small amounts of M3H and  traces of H2H2. The H and M subunits are quite similar in molecular weight,  but differ substantially in amino acid composition. Rabbit muscle LDH dissociates into dimeric species (MW = ~70 kDa) in acetate-chloride at pH  5.0, the dissociation is reversible. Biochemistry, 13, 3527-3531 (1974). Oxidizes glyoxylate and lactate.

Isoelectric point: 8.4-8.6

Optimal pH : 7.5 .

有效单位定义

One unit will reduce 1.0 μmole of pyruvate to L-lactate per min at pH 7.5 at 37 °C.
