Abstract

This invention describes a series of recombinant Thermoanaerobacterium saccharolyticum glucose isomerases having improved catalytic activity and thermostability. The recombinant glucose isomerases can be used for direct production of fructose syrup containing 55 wt % or higher concentration of fructose, or used for the production of fructose syrup containing less than 55 wt % fructose.
