Ribulose bisphosphate carboxylase large chain, Form I; Ribulose bisphosphate carboxylase (Rubisco) plays an important role in the Calvin reductive pentose phosphate pathway. It catalyzes the primary CO2 fixation step. Rubisco is activated by carbamylation of an active site lysine, stabilized by a divalent cation, which then catalyzes the proton abstraction from the substrate ribulose 1,5 bisphosphate (RuBP) and leads to the formation of two molecules of 3-phosphoglycerate. Members of the Rubisco family can be divided into 4 subgroups, Form I-IV , which differ in their taxonomic distribution and subunit composition. Form I is the most abundant class, present in plants, algae, and bacteria, and forms large complexes composed of 8 large and 8 small subunits.

ribulose bisphosphate carboxylase, type III; Members of this protein family are the archaeal, single chain, type III form of ribulose bisphosphate carboxylase, or RuBisCO. Members act is a three-step pathway for conversion of the sugar moiety of AMP to two molecules of 3-phosphoglycerate. Many of these species use ADP-dependent sugar kinases, which form AMP, for glycolysis. [Energy metabolism, Sugars]
