Method for producing 2-keto-l-gulonic acid and vitamin c while using l-sorbose dehydrogenase and l-sorbosone dehydrogenase

摘要

The invention relates to polypeptides having an L-sorbose dehydrogenase (SDH) or L-sorbosone dehydrogenase (SNDH) activity and nucleic acid sequences that code for these polypeptides. The invention also relates to transgenic expression contructs, vectors and transgenic organisms containing these nucleic acid sequences, and to methods for producing 2-keto-L-gulonic acid or ascorbic acid while using the same.
