Protein
Digalactosyldiacylglycerol synthase 2, chloroplastic
Organism
Arabidopsis thaliana
Function
Involved in the synthesis of diacylglycerol galactolipids that are specifically found in thylakoid membranes. Specific for alpha-glycosidic linkages (PubMed:11696551, PubMed:14600212). During phosphate shortage, involved in the biosynthesis of digalactosyldiacylglycerol (DGDG) which rescues the limitation of phospholipids (Probable).
Similarity
Belongs to the glycosyltransferase group 1 family. Glycosyltransferase 4 subfamily.
