Table 3.

Kinetic constants for pyruvate reduction and lactate oxidation reactions of LDHA. Kinetic constants were determined in 0.1 M Tris–maleate (pH 7.0) with 1 mM FBP at 30 °C.

Substrate Km value (mM) Vm value (μmol min−1 mg−1)
NADH 0.066 ± 0.008 1534 ± 45
Pyruvate 1.95 ± 0.12
NAD 0.38 ± 0.01 313 ± 3
l-Lactate 158 ± 4
