Protein
UDP-arabinopyranose mutase 3
Organism
Oryza sativa subsp. japonica
Function
UDP-L-arabinose mutase involved in the biosynthesis of cell wall non-cellulosic polysaccharides. Catalyzes the interconvertion of UDP-L-arabinopyranose (UDP-Arap) and UDP-L-arabinofuranose (UDP-Araf). Preferentially catalyzes the formation of UDP-Arap from UDP-Araf. At thermodynamic equilibrium in vitro the ratio of the pyranose form over the furanose form is 90:10. Is probably active as heteromer in vivo.
Similarity
Belongs to the RGP family.
