Enzymic transfer of α-L-arabinopyranosyl residues to exogenous 1,4-linked β-D-galacto-oligosaccharides using solubilized mung bean (Vigna radiata) hypocotyl microsomes and UDP-β-L-arabinopyranose


A single α-L-arabinopyranosyl (α-L-Arap) residue was shown, by a combination of chemical and spectroscopic methods, to be transferred to O-4 of the nonreducing terminal galactosyl (Gal) residue of 2-aminobenzamide (2AB)-labeled galacto-oligosaccharides when these oligosaccharides were reacted with UDP-ß-L-arabinopyranose (UDP-ß-L-Arap) in the presence of a… (More)
