Expression, Purification and Crystallization of Recombinant Arabidopsis Monogalactosyldiacylglycerol Synthase (MGD1)
Authors:  Joana Rocha, Valerie Chazalet and Christelle Breton, date: 12/20/2016, view: 5552, Q&A: 0
In plant cells, galactolipids are predominant, representing up to 50% of the lipid content in photosynthetic tissues. Galactolipid synthesis is initiated by MGDG synthases (MGDs), which use UDP-galactose as a donor sugar and diacylglycerol (DAG) as ...
