A	ribulose-bisphosphate carboxylase (type I) M-CSA #907	Ribulose-1,5-bisphosphate carboxylase catalyses the only known mechanism whereby atmospheric carbon dioxide is fixed by living organisms. This enzyme is one of the most abundant on Earth, and of great economic importance. The enzyme has two types of subunit, the large are chloroplast encoded and the small subunit (of unknown function) is nuclear encoded. The active site contains a magnesium atom.
