SEQUENCE DB
SOURCE
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
