DNA constructs and methods of producing xylose isomerase

摘要

The present invention relates xylose isomerases obtainable from strains of Thermotoga. More specifically the invention provides DNA sequences encoding xylose isomerases, expression vectors and host cells comprising the DNA sequences of the invention, and methods of producing xylose isomerases. The invention also provides isolated xylose isomerases free from homologous impurities and obtained by the method of the invention.
