comment
  • 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.CATALYTIC ACTIVITY UDP-beta-L-arabinofuranose = UDP-beta-L-arabinopyranoseCOFACTOR Optimum pH is 5.5-6.0.SUBUNIT Heteromers with UAM2 and UAM3.SUBCELLULAR LOCATION The conserved DXD motif is involved in enzyme activity.PTM Reversibly glycosylated in vitro at Arg-158 by UDP-glucose. Reversibly glycosylated by UDP-xylose and UDP-galactose.SIMILARITY Belongs to the RGP family.SEQUENCE CAUTION Truncated N-terminus.
