text: The conversion of malate to pyruvate and lactate is catalyzed by
  *NAD(P) dependent malate decarboxylase (malic enzyme; EC 1.1.1.39 and 1.1.1.40) and
  *lactate dehydrogenase (LDH; EC 1.1.1.27)
  according to the following equations:
  *malate + NAD(P)→ pyruvate + NAD(P)H + H + CO
  *pyruvate + NADH + H → lactate + NAD
