Title: NOVEL α-GLUCOSIDASE
Abstract:
The present invention addresses the problem of providing a novel α-glucosidase which has high heat resistance and is highly active in producing a saccharide having consecutive α-1,6 bonds. This α-glucosidase was discovered from Aspergillus sojae, which is a species of bacteria belonging to the genus Aspergillus. The α-glucosidase was found to act on various α-type oligosaccharides and α-type polysaccharides and is highly active in producing saccharides having consecutive α-1,6 bonds. Furthermore, the α-glucosidase was found to exhibit high heat resistance in that 90% or more of activity remains after being stored for one hour at 50˚C.
