plant-type phytoene desaturase
Systematic name
15-cis-phytoene:plastoquinone oxidoreductase
Comment
This enzyme is involved in carotenoid biosynthesis in plants and cyanobacteria. The enzyme from Synechococcus can also use NAD+ and NADP+ as electron acceptor under anaerobic conditions. The enzyme from Gentiana lutea shows no activity with NAD+ or NADP+ [1].
