NCBI Protein Information
NAD(P)-binding Rossmann-fold superfamily protein
NCBI Summary
encodes a type-II membrane protein that catalyzes 4-epimerization of UDP-D-Xylose to UDP-L-Arabinose in vitro, the nucleotide sugar used by glycosyltransferases in the arabinosylation of cell wall polysaccharides and wall-resident proteoglycans.
UniProt Protein Name
