Chloroplasts are endosymbiotic organelles derived from cyanobacteria. They have a double envelope membrane, including the outer envelope and the inner envelope. A complex membrane system, thylakoids, exists inside the chloroplast. It is the site of the light-dependent reactions of photosynthesis. The stroma is the main site of the carbon fixation reactions. Although photosynthesis is a very complicated process with many proteins involved, there are many other important processes that occur in chloroplasts, including the regulation of photosynthesis, the biogenesis and maintenance of the structures, carbohydrate, lipid, tetrapyrrole, amino acid, and isoprenoid metabolism, production of some phytohormones, production of specialized metabolites, …

Galactolipids [monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol
(DGDG)] are the hallmark lipids of photosynthetic
membranes. The galactolipid synthases MGD1 and DGD1
catalyze consecutive galactosyltransfer reactions but localize to the
inner and outer chloroplast envelopes, respectively, necessitating
intermembrane lipid transfer. Here we show that the N-terminal
sequence of DGD1 (NDGD1) is required for galactolipid transfer
between the envelopes. Different diglycosyllipid synthases (DGD1,
DGD2, and Chloroflexus glucosyltransferase) were introduced into
the dgd1-1 mutant of Arabidopsis in fusion with N-terminal extensions
(NDGD1 and NDGD2) targeting to the outer envelope. Reconstruction
of DGDG synthesis in the outer envelope membrane was
observed only with diglycosyllipid synthase fusion …
