ABSTRACT:
This invention relates to heat resistant maltose phosphorylase having an activity of 80% or more of the one untreated after treated in a buffer of pH 6.0, at one temperature of 50 to 60.degree. C. for 15 minutes, a process for preparation thereof, bacteria used for preparation thereof, and processes for preparation of .beta.-glucose-1-phosphoric and trehalose using the enzyme.
By carrying out enzymatic reaction at high reaction temperatures using this enzyme, it is possible to prepare .beta.-glucose-1-phosphoric acid or trehalose industrially advantageously, with lowering of contamination with various germs and shortening of reaction time.
