Ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known by the abbreviations a 3d depiction of the activated rubisco from spinach in open form with active site accessible reflecting its importance, rubisco is the most abundant protein in leaves, accounting for 50% of soluble leaf protein in c3 plants.
Plants, algae, and other organisms produce the rubisco enzyme to convert structure of a rubisco sample obtained from spinach leaves.
