1.3.1.83 geranylgeranyl diphosphate + NADPH + H+ Arabidopsis thaliana 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 reductase gene is up-regulated during etioplast to chloroplast and chloroplast to chromoplast development phytyl diphosphate + NADP+
