Protein
UDP-arabinopyranose mutase 3
Gene
RGP3, At3g08900, T16O11.16
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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 95:5. Is not active on other UDP-sugars (UDP-Gal, UDP-Xyl, UDP-Glc, GDP-Man and GDP-Fuc). Is probably active as heteromer in vivo.1 Publication

Catalytic activityi

UDP-beta-L-arabinofuranose = UDP-beta-L-arabinopyranose.

Cofactori

Manganese or Magnesium By similarity.
