Abstract
After a bibliographic review of the properties of RuBP-carboxylase/oxygenase, a methodology is described which allows the treatment of a large number of samples for the assay of the enzyme activity. 14{sup C}O{sub 3}HNa is used as a marker for the counting of the incorporated radioactivity as acid insoluble material. 14''CC{sub 2} from the labeled sodium bicarbonate is the species used by the enzyme both as an activator as well as a substrate. The following experiments are described and its results given: Determination of the optimal conditions for the activation of the enzyme; study of the kinetics of the catalytic action; effect of the Mg{sup 2} concentration and determination of the Km{sub (s)} from CO{sub 2} and ribulose 1,5-biphosphate; also determination of the optimum pH at different concentrations of CO{sub 2}2 and Mg{sup 2}.
