Significance Enzymes of the chlorophyll biosynthetic pathway, which bind protoporphyrin and Mg-porphyrins, are susceptible to damage by singlet oxygen production in the presence of light and oxygen. These studies show that heme-derived linear tetrapyrroles (bilins) both stimulate and protect the pro...
