Rubisco is a bifunctional enzyme catalyzes the ini tial steps of two opposing metabolic pathways: photosynthetic carbon fixation and the competing process of photorespiration. The RUBP means Ribulose Bisphosphate. Cookies help us deliver our services. Carboxylase definition is - an enzyme that catalyzes decarboxylation or carboxylation. RuBP stands for ribulose bisphosphate, it's a 5 carbon compound involved in the Calvin cycle, which is part of the light independent reactions of photosynthesis. The fructose 6-phosphate formed is then converted to fructose 1,6-bisphosphate, which is subsequently metabolized into pyruvate via the glyco-lytic pathway (cleavage stage). D-Ribulose 1,5-diphosphate carboxylase from spinach has also been used in a study to determine RuBisCO activation kinetics and other rate and equilibrium constants by simultaneous multiple non-linear regression of a kinetic model. It is an intermediate in photosynthesis. An enzyme called rubisco combines CO2 with a molecule called ribulose bisphosphate (RuBP, a 5-C molecule) to create an unstable 6-C molecule that is immediately split into 2 three-C molecules called 3-phosphoglycerate (3-PGA). The C O 2 is fixed in a number of steps using C O 2 acceptor RuBP (ribulose bisphosphate). a ketopentose whose phosphate derivatives participate in photosynthesis. Medical Information Search.
