Abstract
The present invention has an object to provide a D-mannose isomerase of membrane-bound form having the optimal reaction pH in acidic region. The membrane-bound D-mannose isomerase derived from acetic acid bacteria is produced. The acetic acid bacteria are preferably belong to the genera of Acetobacter, Gluconobacter, or Gluconacetobacter. Furthermore, the membrane-bound D-mannose isomerase from the acetic acid bacteria is used to produce D-fructose from D-mannose.
Claims13
A membrane-bound D-mannose isomerase derived from acetic acid bacteria.
A method of producing a membrane-bound D-mannose isomerase comprising culturing acetic acid bacteria in a nutrition medium, and then obtaining bacterial cells, or preparing the cytoplasmic membrane fraction from the bacterial cells thus obtained.
