Mg-chelatase

Mg-chelatase is an enzyme involved in plant chlorophyll production. It helps insert magnesium ions into a molecule called protoporphyrin IX, which is a crucial step in forming chlorophyll—the pigment that captures sunlight for photosynthesis. By facilitating this magnesium insertion, Mg-chelatase plays a key role in the plant’s ability to produce energy from sunlight, supporting growth and development. It acts as a molecular gatekeeper, ensuring the proper flow of reactions needed to synthesize chlorophyll efficiently.
