General Information

EC Number General Information Comment Organism
1.14.13.122 physiological function enzyme overexpression results in increased chlorophyll b synthesis and a decreased chlorophyll a/b ratio in low light-grown as well as high light-grown tobacco plants. This effect, however, is more pronounced in high light. Enzyme overexpression affects the chlorophyll biosynthetic flux by modulating the gene and protein expression of several other chlorophyll biosynthetic pathway enzymes (i.e. Mg-protoporphyrin IX:S-adenosyl-Met methyltransferase) Arabidopsis thaliana
