D 2 O solvent isotope effects suggest uniform energy barriers in ribulose-1,5-bisphosphate carboxylase/oxygenase catalysis
D-Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is the most abundant enzyme on Earth and is responsible for the fixation of atmospheric CO2 into biomass. The reaction consists of incorporation of CO 2 and solvent H2O into d-ribulose 1,5-bisphosphate (RuBP) to yield 3-phospho-d-glycerate. The reaction involves several proton-dependent events: abstraction and protonation during enolization of RuBP and hydrolysis and reprotonation of the six-carbon reaction intermediate...[Show more]
