General Information

General Information	Comment	Organism
malfunction	enzyme deficiency due to a recessive mutation G206S in gene CHLP leads to the yellow-green leaf mutant 502ys. The mutant exhibits reduced level of Chls, arrested development of chloroplasts, and retarded growth rate, phenotype, overview. The mutant phenotype is complemented by transformation with the wild-type gene	Oryza sativa Japonica Group
metabolism	the enzyme is involved in the reduction step from Chl-geranylgeranylated (ChlGG) and geranylgeranyl diphosphate (GGPP) to Chl-phytol (ChlPhy) and phytyl diphosphate (PPP) in rice	Oryza sativa Japonica Group
physiological function	geranylgeranyl reductase (CHL P) catalyzes the reduction of geranylgeranyl diphosphate to phytyl diphosphate, and provides phytol for both Chlorophyll (Chl) and tocopherol synthesis. The enzyme is involved in the reduction step from Chl-geranylgeranylated (ChlGG) and geranylgeranyl diphosphate (GGPP) to Chl-phytol (ChlPhy) and phytyl diphosphate (PPP) in rice	Oryza sativa Japonica Group
