Substrate Specificities of α-Galactosidase from Rice

Abstract:

Article Preview

The α-galactosidase from rice cleaved not only α-D-galactosyl residues from the non-reducing end of substrates such as melibiose, raffinose and stachyose, but also liberated the terminal galactosyl residues attached O-6 position of the reducing-end mannosyl residue in mannobiose and mannotriose. In addition, the enzyme tore off the stubbed galactosyl residues attached inner-mannosyl residues in mannopentaose. It also could catalyze efficient degalactosylation of galactomannans, such as guar gum and locust bean gum.
