This enzyme is degraded by the actions of victorin and the DNA-binding aspartic acid peptidase CND41, but is forced into a proteolysis-resistant state by the binding of its inhibitor CA1P. It is usually localized to to pyrenoids, and a lysine residue on it is carbamated by its namesake activase, which allows the positioning of a critical magnesium molecule. Phosphoglycolate is a side product of this enzyme, whose slow speed and penchant for leading to photorespiration is counteracted by PEP carboxylase in some organisms. FTP, name this enzyme, the most abundant protein on earth, that catalyzes a major step in the Calvin cycle by attaching a carbon dioxide molecule to Ribulose bisphosphate.
