Trehalose phosphorylase its preparation and uses |
摘要 |
A thermostable trehalose phosphorylase which is obtainable from microorganisms of the genus Thermoanaerobium and which hydrolyzes trehalose in the presence of an inorganic phosphoric acid to form D-glucose and beta -D-glucose-1-phosphoric acid. The trehalose phosphorylase can be also prepared by recombinant DNA technology. When the enzyme is allowed to contact with beta -D-glucose-1-phosphoric acid as a saccharide donor in the presence of other saccharides, glucosyl-transferred saccharides including glucosyl-D-galactoside, which are conventionally known but scarcely obtainable, can be produced on an industrial-scale and in a relatively-low cost.
