EC Number | Protein Variants | Comment | Organism |
---|---|---|---|
3.2.1.3 | A246C | the T50-value is enhanced by 4°C to 73°C. Compared to wild-type enzyme, the mutant is twice as active at 66°C but half as active at 45°C | Aspergillus awamori |
3.2.1.3 | C320A | barely improved thermostability or altered activity | Aspergillus awamori |
3.2.1.3 | P307A/T310V/Y312M/N313G | up to 15fold decreased turnover-number for alpha-1,4-linked substrates. Up to 9fold increase in Km-value for alpha-1,6-linked substrates | Aspergillus awamori |
3.2.1.3 | V181T/N182Y/G183A | 2fold increased Km-value for alpha-1,4-linked substrates: For alpha-1,6-linked substrates a 2fold increase in Km and a 3fold decrease in turnover-number | Aspergillus awamori |
3.2.1.3 | V181T/N182Y/G183A/P307A/T310V/Y312M/A313G | remarkably low Km-value for isomaltotriose through isomaltoheptaose and elevated turnover-number on isomaltose, resulting in an approximately 2fold improved catalytic effeciency | Aspergillus awamori |
