A reaction catalyzed by this enzyme forms an endoperoxide that spontaneously hydrates, is cleaved into 2-phosphoglycolate, and eventually forms serine.
A reaction catalyzed by this enzyme forms an endoperoxide that spontaneously hydrates, is cleaved into 2-phosphoglycolate, and eventually forms serine. This enzyme is regulated by CA1P, a transition state analog synthesized by its namesake activase. This enzyme is only active at high pHs and requires a magnesium cation cofactor to coordinate an intermediate carbamate. It has an extremely low turnover number of 3 inverse-seconds. 3-phosphoglycerate is a product of one of its reactions. This enzyme, which is present in mesophyll but not bundle-sheath cells in C4 plants, can catalyze photorespiration at low carbon dioxide levels. It makes up the majority of protein leaves. For 10 points, name this most abundant protein on Earth, which is vital for the Calvin Cycle.
