Protein Variants
| EC Number | Protein Variants | Comment | Organism |
|---|---|---|---|
| 5.3.1.1 | S211A | mutation eliminates intraloop hydrogen bonds to the side-chain hydroxyl, 60fold decrease in kcat/Km | Saccharomyces cerevisiae |
| 5.3.1.1 | S211G | mutation eliminates intraloop hydrogen bonds to the side-chain hydroxyl, leading to small changes in the kinetic parameters | Saccharomyces cerevisiae |
| 5.3.1.1 | Y208A | main effect of mutations is to cause a reduction in the total intrinsic dianion binding energy | Saccharomyces cerevisiae |
| 5.3.1.1 | Y208F | mutation eliminates the intraloop hydrogen bond between the hydroxyl group of Y208 and the amide nitrogen of A176. Enzyme activity is reduced by ca. 50fold compared to the Y208A and Y208S mutants | Saccharomyces cerevisiae |
| 5.3.1.1 | Y208S | main effect of mutations is to cause a reduction in the total intrinsic dianion binding energy | Saccharomyces cerevisiae |
| 5.3.1.1 | Y208T | main effect of mutations is to cause a reduction in the total intrinsic dianion binding energy | Saccharomyces cerevisiae |
| 5.3.1.1 | Y208T/S211G | tenfold decrease in kcat/Km | Saccharomyces cerevisiae |
