Chemical synthesis of UDP-beta-L-arabinofuranose and its turnover to UDP-beta-L-arabinopyranose by UDP-galactopyranose mutase.
Uridine-5'-diphospho-beta-L-arabinofuranose, a possible donor of L-arabinofuranose residues in plants, was synthesized. This compound, in the presence of UDP-galactopyranose mutase, underwent interconversion with UDP-beta-L-arabinopyranose that is a likely precursor of L-arabinofuranose in vivo. This result provided a working model for the biogenesis of arabinofuranose in plants.
