in etiolated seedlings white light induces a transient increase in MGD mRNA, followed by a subsequent increase in enzyme activity. When cotyledons were detached from seedlings, these light-induced changes diminished |

MGDG synthase catalyzes the final step in thylakoid membrane lipid monogalactosyldiacylglycerol, MGDG, biosynthesis in the plastid envelope |
| 2.4.1.46 | more |
mono- and digalactosyldiacylglycerol constitute the bulk of membrane lipids in plant chloroplasts and are essential for chloroplast biogenesis and photoautotrophic growth. Type B monogalactosyldiacylglycerol synthases are involved in phosphate starvation-induced lipid remodeling and are crucial for low-phosphate adaptation, overview |
| 2.4.1.46 | more |
regulation of MGDGsynthesis by phosphatidic acid, which is a general precursor in the synthesis of all glycerolipids and is also a signaling molecule in plants |

| 2.4.1.46 | UDP-galactose + 1,2-diacyl-sn-glycerol |
type B MGDG synthases may have roles during pollen germination and pollen tube growth and may be acting primarily to supply MGDG as a precursor for DGDG synthesis. Expression of atMGD2 and atMGD3, but not atMGD1, is strongly induced during phosphate starvation, particularly in roots |
| 2.4.1.46 | UDP-galactose + 1,2-diacyl-sn-glycerol |
MGD activity is reversibly regulated by reduction and oxidation in vitro |
| 2.4.1.46 | UDPgalactose + 1,2-diacylglycerol |
involved in biosynthesis of monogalactosyldiacylglycerol |
| 2.4.1.46 | UDPgalactose + 1,2-diacylglycerol |
enzyme is responsible for the biosynthesis of monogalactosyl diglyceride in brain and may function significantly in myelination |
| 2.4.1.46 | UDPgalactose + 1,2-diacylglycerol |
last step in monogalactosyldiacylglycerol biosynthesis |
