purified 557 kDa hexadecamer Rubisco protein complex from Spinacia oleracea (SIGMA-ALDRICH R-8000), UniProt: P00875 and Q43832
Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyzes the rate-limiting step of CO2 fixation in photosynthetic organisms. It is demonstrably homologous from purple bacteria to flowering plants and consists of two protein subunits, each pres
