Abstract

The rice branching enzyme I (BEI) overproduced in Escherichia coli cells was investigated with respect to action on starches. BEI treatment decreased the turbidity of starch suspensions with distinct pasting behaviors from a native starch. This result suggests the great potential of BEI as a molecular tool for the production of a novel glucan polymer.
