Enzymes for the production of 2-keto-L-gulonic acid |
| 摘要 |
Mutants of 2,5-diketo-D-gluconic acid reductase A, an enzyme used to produce 2-keto-L-gulonic acid, a precursor of ascorbic acid (vitamin C) are prepared by site-directed mutagenesis. These mutants have increased catalytic activity, increased expression levels, and/or enhanced temperature stability.
