One enzyme requires the post-translational modification of this molecule binding to a lysine residue, allowing for coordination of a magnesium ion to the active site.
One enzyme requires the post-translational modification of this molecule binding to a lysine residue, allowing for coordination of a magnesium ion to the active site. This compound competes with oxygen to bind to an enzyme that usually produces two molecules of phospho-glycerate. Sometimes, this compound is stored in malate and released to the bundle-sheath cells. Photorespiration is caused when RuBisCO binds to oxygen instead of this compound. Carbonic anhydrase converts this gas to carbonic acid. This gas is the source of carbon in carbon fixation through the Calvin cycle. For 10 points, name this gas that is used up in photosynthesis and released in respiration.
