| additional information | monogalactosyldiacylglycerol is ubiquitous in the photosynthetic membranes of cyanobacteria and chloroplasts. It is synthesized by galactosylation of diacylglycerol in the chloroplasts, whereas it is produced by epimerization of monoglucosyldiacylglycerol in at least several cyanobacteria | Synechocystis sp. |

It is synthesized by galactosylation of diacylglycerol in the chloroplasts, whereas it is produced by epimerization of monoglucosyldiacylglycerol in at least several cyanobacteria. The N-terminal fatty acid hydroxylase domain is lacking in the MgdE protein of Prochlorococcus marinus. The monoglucosyldiacylglycerol level is very low in Prochlorococcus marinus, but it is about 1/50 of that of monogalactosyldiacylglycerol in most cyanobacteria | Prochlorococcus marinus |
