| PEP carboxylase | <enzyme> Enzyme responsible for the primary fixation of carbon dioxide in C4 plants. Carboxylates PEP phosphoenolpyruvate to give oxaloacetate. Also important in crassulacean acid metabolism, since it is responsible for carbon dioxide fixation in the dark. (18 Nov 1997) |
| ribulose-1,5-bisphosphate carboxylase | A dimerizing carboxy-lyase; an enzyme that catalyses the addition of carbon dioxide to d-ribulose 1,5-bisphosphate and the hydrolysis of the addition product to two molecules of 3-d-phosphoglyceric acid, a key reaction in the fixation of CO2 in photosynthesis. Synonym: carboxydismutase. (05 Mar 2000) |
| ribulose-1,5-bisphosphate carboxylase-oxygenase large subunit epsilonN-methyltransferase | <enzyme> An aspect of EC 2.1.1.43; trimethylates lys-14 of rubisco Registry number: EC 2.1.1.- Synonym: rubisco lsmt, rubisco large subunit lysine n-methyltransferase (26 Jun 1999) |
| ribulose bisphosphate carboxylase | <enzyme> A copper protein that catalyses the formation of 2 moles of 3-phosphoglycerate from ribulose 1,5-biphosphate in the presence of carbon dioxide and is responsible for carbon dioxide fixation in photosynthesis. Carbon dioxide is combined with ribulose diphosphate to give two molecules of 3 phosphoglycerate, as part of the Calvin Benson cycle. It is the sole carbon dioxide fixing enzyme in C3 plants and collaborates with PEP carboxylase in carbon dioxide fixation in C4 plants. In the presence of oxygen the products of the reaction are one molecule of phosphoglyceric acid and one molecule of phosphoglycolic acid. The latter is the initial substrate for photorespiration and this oxygenase function occurs in C3 plants where the enzyme is not protected from ambient oxygen, in C4 plants the enzyme acts exclusively as a carboxylase since it is protected from oxygen. Also called Fraction 1 protein, the major protein of leaves. Chemical name: 3-Phospho-D-glycerate carboxy-lyase (dimerizing) Registry number: EC 4.1.1.39 (12 Dec 1998) |

| ribulose diphosphate carboxylase | <enzyme> A copper protein that catalyses the formation of 2 moles of 3-phosphoglycerate from ribulose 1,5-biphosphate in the presence of carbon dioxide and is responsible for carbon dioxide fixation in photosynthesis. Carbon dioxide is combined with ribulose diphosphate to give two molecules of 3 phosphoglycerate, as part of the Calvin Benson cycle.

| phosphoenolpyruvate carboxylase | <enzyme> An enzyme with high affinity for carbon dioxide. It catalyses irreversibly the formation of oxaloacetate from phosphoenolpyruvate and carbon dioxide. This fixation of carbon dioxide in several bacteria and some plants is the first step in the biosynthesis of glucose.

| carboxylase |
an enzyme that catalyzes the addition of a molecule of carbon dioxide to another compound to form a carboxyl group. The carboxylases include some carboxy-lyases [EC 4.1.1] and those ligases, usually biotinyl-proteins, that cleave ATP to drive the reaction [EC 6.4.1].
