Outline of Final Research Achievements |
We found the CDP-glycerol (CDP-Gro), which is a novel sugar alcohol nucleotide donor in mammals, and identified that the PCYT2 is CDP-Gro synthase. The biosynthesis of functional O-mannosyl glycans require the formation of tandem ribitol phosphate structure by transfer from CDP-ribitol (CDP-Rbo), but glycerol phosphate (GroP) transferred from CDP-Gro inhibited the formation of tandem ribitol phosphate structure. We also determined the crystal structures of POMGNT2, POMK, and FKRP, which are biosynthetic enzymes of O-mannosyl glycans in mammals, revealing the detailed mechanism of the glycosylation by each enzyme.
