Protein Variants | Comment | Organism |
---|---|---|
F42C | mutant retains more than 70% of activity after 1 h, while the wild-type enzyme retains only 10% activity. Optimal temperature of mutant enzyme is about 10°C higher than that of wild-type enzyme. Activity at the optimal temperature is about 20% higher than that of wild-type enzyme. KM-values for D-Ala, D-Met, D-Phe and D-Ser are 40-50% of the wild-type value | Sus scrofa |
