| Sysname |
UDP-galactose:1,2-diacyl-sn-glycerol 3-beta-D-galactosyltransferase |
| Reaction(IUBMB) |
UDP-galactose + 1,2-diacyl-sn-glycerol = UDP +
3-beta-D-galactosyl-1,2-diacyl-sn-glycerol [RN:R02691] |
| Reaction(KEGG) |
R02691
 |
| Substrate |
UDP-galactose [CPD:C00052];
1,2-diacyl-sn-glycerol [CPD:C00641] |
| Product |
UDP [CPD:C00015];
3-beta-D-galactosyl-1,2-diacyl-sn-glycerol |
| Comment |
This enzyme adds only one galactosyl group to the diacylglycerol; EC
2.4.1.241, digalactosyldiacylglycerol synthase, adds a galactosyl
group to the product of the above reaction. There are three isoforms
in Arabidopsis that can be divided into two types, A-type (MGD1) and
B-type (MGD2 and MGD3). MGD1 is the isoform responsible for the bulk
of monogalactosyldiacylglycerol (MGDG) synthesis in Arabidopsis [4]. |
