A406L | the mutant shows higher thermostability at 35-40°C, higher intermolecular transglucosylation activity with an upward shift in the optimum temperature and a slight increase in the optimum pH for disproportionation and cyclization reactions compared to the wild type enzyme. The mutant shows higher specific activities for starch transglucosylation (2.1fold) and disproportionation (1.4fold) than those of the wild type | Corynebacterium glutamicum |
A406V | the mutant shows higher thermostability at 50°C, higher intermolecular transglucosylation activity with an upward shift in the optimum temperature and a slight increase in the optimum pH for disproportionation and cyclization reactions compared to the wild type enzyme. The mutant shows higher specific activities for starch transglucosylation (2.8fold) and disproportionation (2.1fold) than those of the wild type | Corynebacterium glutamicum |
