inactivation of the gene chlP encoding the enzyme in Synechocystis sp. PCC 6803. The resulting DELTAchlP mutant accumulates exclusively geranylgeranylated chlorophyll a instead of its phytylated analogue as well as low amounts of alpha-tocotrienol instead of alpha-tocopherol. Whereas the contents of chlorophyll and total carotenoids are decreased, abundance of phycobilisomes is increased in DELTAchlP cells. The mutant assembles functional photosystems I and II as judged from 77 K fluorescence and electron transport measurements. The mutant is unable to grow photoautotrophically due to instability and rapid degradation of the photosystems in the absence of added glucose. It is suggested that instability of the photosystems in DchlP is directly related to accumulation of geranylgeranylated chlorophyll a
UniProt
reduction in enzyme activity in transgenic Nicotiana tabacum plants is accompanied by the reduction in total chlorophyll and tocopherol content and the accumulation of geranylgeranylated chlorophyll. The presence of geranylgeranylated chlorophyll has no influence on harvesting and transfer of light energy in either photosystem. However, the reduced tocopherol content of the thylakoid membrane is a limiting factor for defensive reactions to photo-oxidative stress

physiological function

DGGR catalyzes a critical step in the biosynthesis of archaeal membrane lipids. The saturation of hydrocarbon chains confers the ability to resist hydrolysis and oxidation and helps archaea withstand extreme conditions

malfunction
-
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

due to its multifunctionality and weak hydrophobicity, it is suggested that in plastids the same geranylgeranyl reductase is recruited into the chlorophyll, the tocopherol and the phylloquinone pathways.

the geranylgeranyl diphosphate reductase message is abundant in chlorophyll-containing tissues and flower organs, but barely detected in the roots and mesocarp of ripening fruits, suggesting that transcription is related to plastid types and maturation
the geranylgeranyl diphosphate reductase mRNA is abundant in chlorophyll-containing tissues and flower organs, but barely detected in the roots and mesocarp of ripening fruits, suggesting that transcription is related to plastid types and maturation. mRNA is spread thoroughly in leaf cells during the early stages and is located mainly in the palisade of mature leaves, which exhibit higher transcript levels than young ones. Hence, the transcription of geranylgeranyl diphosphate reductase is likely to be regulated during leaf development. Transcription is stimulated by light, but repressed by dark and cold stress. In wounded leaves, the message decreases, but recovers rapidly, whereas in curled leaves, a reduction in gene expression is related to leaf damage intensity
