Functional Family Ribulose bisphosphate carboxylase small chain, chloroplastic

Enzyme Information

4.1.1.39
Ribulose-bisphosphate carboxylase.
based on mapping to UniProt P69249
2 3-phospho-D-glycerate + 2 H(+) = D-ribulose 1,5-bisphosphate + CO(2) + H(2)O.
-!- Will utilize O(2) instead of CO(2), forming 3-phospho-D-glycerate and 2-phosphoglycolate.
