Table 1. Concentration of different substrates used for the determination of Km for various substrates.

Rabbit muscle triose phosphate isomerase (1 U/mL) was added and an equilibrium ratio of 18:1 for DHAP:GAP was used to assign a concentration of GAP.

Substrate tested (for determination of Km) Concentration of substrates used in each reaction
ThDP (mM) DHAP (μM) Pyruvate (mM)
ThDP 0‒1 263 5
GAP 0.1 0–197 5
Pyruvate 0.1 263 0–1
