Abstract
Described herein are novel nucleic acids, proteins and methods that can be used to provide new catalysts with desirable traits for industrial processes. In particular, novel reductases isolated from the environment using PCR methods are described.
Claims1
A process for converting glucose to ascorbic acid comprising culturing a host cell comprising a nucleotide sequence which encodes a peptide having an amino acid sequence which has at least about 95% sequence identity to an amino acid sequence of SEQ ID NO:
- 10, wherein said conversion of glucose to acid acid is conducted under conditions suitable for the expression of 2,5-diketo-D-gluconic acid reductase.
