Magnesium dechelatase
From Wikipedia, the free encyclopedia
Magnesium dechelatase is a lyase enzyme that removes magnesium from chlorophyll a in plants to form pheophytin a. Its gene is Stay-Green,[1] which is linked to the green cotyledon trait studied by Gregor Mendel.[2] Its putative structure was deduced in 2021, and it is predicted to be a homo-oligomer.[3]
