Protein
UDP-D-xylose:L-fucose alpha-1,3-D-xylosyltransferase 3
Organism
Arabidopsis thaliana
Function
Catalyzes the transfer of D-xylose from UDP-alpha-D-xylose onto L-fucose. Probably involved in the biosynthesis of rhamnogalacturonan II (RG-II) through xylosylation of the internal fucose moiety of the A-chain of RG-II, a structurally complex pectic polysaccharide of the primary cell wall. RG-II is essential for the cell wall integrity of rapidly growing tissues such as roots and pollen tube growth and elongation.
Similarity
Belongs to the glycosyltransferase 77 family.
