TL;DR: Kinetic properties of soybean net photosynthetic CO(2) fixation and of the carboxylase and oxygenase activities of purified soybean ribulose 1, 5-diphosphate carboxyase were examined and showed equality of kinetic constants, consistent with the notion that the same enzyme catalyzes both reactions.

TL;DR: From analyses of RuBP carboxylase/oxygenase enzymes purified from several different species, large differences in specificity towards the substrates CO2 and O2 are reported.

TL;DR: It is suggested that the phosphoglycolate produced in this reaction is the source of glycolate metabolized in photorespiration.

TL;DR: Breeding experiments indicate that it will be difficult, if not impossible, to transform photorespiratory C3 species into non-photorespiratories C4 species, and control of photorespiration will have to be achieved by isolating photore Spiratory-deficient mutants of C3 plants or by identifying chemical compounds that specifically inhibit photorepiratory metabolism.

TL;DR: Results indicate that a specific chloroplast enzyme, rubisco activase, catalyzes the activation of rubisco in vivo.
