RGP1_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: RGP1_ARATH
• UniProt AC: Q9SRT9
• Protein Name: UDP-arabinopyranose mutase 1 {ECO:0000305}
• Gene Name: RGP1 {ECO:0000303|PubMed:21478444}
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 357
• Subcellular Localization: Cytoplasm, cytosol. Golgi apparatus. Soluble and associated with peripheral membrane and endomembrane system.
• Protein Description: 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) in vitro. 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). [PubMed: 21478444 Functions redundantly with RGP2 and is essential for proper cell walls and pollen development. Probably involved in the formation of the pectocellulosic cell wall layer intine. Is probably active as heteromer in vivo]
