The Michaelis constants of soya-bean ribulose bisphosphate carboxylase for CO2 in the carboxylation reaction and for O2 in the oxygenation reaction depend on the nature of the bivalent cation present. In the presence of Mg2+ the Km for bicarbonate is 2.48 mM, and the Km for O2 is 37% (gas-phase concentration). With Mn2+ the values decrease to 0.85 mM and 1.7% respectively. For the carboxylation reaction Vmax. was 1.7 mumol/min per mg of protein with Mg2+ but only 0.29 mumol/min per mg of protein with Mn2+. For the oxygenation reaction, Vmax. values were 0.61 and 0.29 mumol/min per mg of protein respectively with Mg2+ and Mn2+.

Mitochondria isolated from spinach (Spinacia oleracea) leaves oxidized glycine with a stoichiometry of CO2 evolution to O2 uptake of 2 : 1. In the absence of added substrate, the mitochondria exhibited an extremely low endogenous rate of O2 uptake.
