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 |

mass spectrometry reveals that cells deleted of HVO_1799 fail to fully reduce the isoprene chains of Hfx. volcanii membrane phospholipids and glycolipids. Likewise, the absence of HVO_1799 leads to a loss of saturation of the omega-position isoprene subunit of C55 and C60 dolichol phosphate, with the effect of HVO_1799 deletion being more pronounced with C60 dolichol phosphate than with C55 dolichol phosphate |

the light-induced yellow leaf 1-1 (lyl1-1) mutant is hypersensitive to high-light and defective in the Chl synthesis. The mutation of LYL1 leads to conjugation of the majority of Chl molecules with an unsaturated geranylgeraniol side chain. The lyl1-1 mutant suffers from severe photooxidative damage and displays a drastic reduction in the levels of alpha-tocopherol and photosynthetic proteins. The yellowing of lyl1-1 mutant is caused by high-light stress. Mutant lyl1-1 phenotype, overview |

| 1.3.1.83 | metabolism |
the three-step hydrogenation of geranylgeranyl diphosphate into phytyl diphosphate, and Chl-geranylgeranylated (ChlGG) and Chl-phytol (ChlPhy) is catalyzed by NADPH-dependent geranylgeranyl reductase. ENzyme LYL1 protects against lipid peroxidation and reactive oxygen species, ROS |

| 1.3.1.83 | 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 |
