But the Zambian government decided to refuse the GM food. We offered our opinion to the Zambian government and, as many governments do, they disregarded our advice." Greenpeace opposes the planned use of golden rice, a variety of "Oryza sativa" rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of pro-vitamin A in the edible
12-oxophytodienoate reductase 12-oxophytodienoate reductase 12-oxophytodienoate reductase (OPRs) is an enzyme of the family of Old Yellow Enzymes (OYE). OPRs are grouped into two groups: OPRI and OPRII – the second group is the focus of this article, as the function of the first group is unknown, but is the subject of current research. The OPR enzyme utilizes the cofactor flavin mononucleotide (FMN) and catalyzes the following reaction in the jasmonic acid synthesis pathway: This reaction occurs in peroxisomes in plants. Several isozymes have been discovered, with varying substrate stereospecificity: three in "Lycopersicon esculentum", 13 in "Oryza sativa", and five in "Arabidopsis thaliana".
