Characteristics of the protein coding sequence
EN
1-deoxy-D-xylulose-5-phosphate synthase catalyzes the acyloin condensation reaction between carbon atoms 2 and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D-xylulose-5-phosphate. This reaction is the rating limiting step in plastidic isoprenoid biosynthesis and essential for chloroplast development. Plants overexpressing this enzyme increased levels of plastid isoprenoids derived from the methylerythritol 4-phosphate pathway, such as chlorophylls, tocopherols, carotenoids, abscisic acid, and gibberellin.
