Table 6 The enzyme efficiency, represented as V max /K m for LDH in partial purified tumor and normal breast tissues

From: Kinetic characterization of lactate dehydrogenase in normal and malignant human breast tissues

  Tumor Normal
Vmax/Km with lactate (mU/mg/mM) 28.92 ± 1.3* 56.1 ± 2.4
Vmax/Km with NAD+ (mU/mg/mM) 1294.94 ± 6.7* 2474 ± 8.1
  1. Assays were conducted at 25°C and data are presented as means ± SEM, n = 3 independent determinations on each of 17 tumor and normal samples. *Significant difference in each row at p < 0.05.
