A process for producing α-glucan from β-1,4-glucan, comprising the step of carrying out reaction of a solution containing β-1,4-glucan, a primer, a phosphoric acid source, β-1,4-glucan phosphorylase and α-1,4-glucan phosphorylase to thereby obtain α-glucan. In this process, the above β-1,4-glucan can be cellobiose, and the above β-1,4-glucan phosphorylase can be cellobiose phosphorylase. |
