Table 3. Enzymatic kinetic parameters of wild-type and mutated CatAs after purification against the substrate catechol*.
Enzymes | Km(μM) | kcat(S−1) |
---|---|---|
WT | 7.88 ± 1.239 | 7.86 ± 0.248 |
L73F | 151.09 ± 10.299 | 5.65 ± 0.163 |
P76A | 65.91 ± 7.753 | 46.56 ± 0.201 |
L73F P76A | 45.96 ± 7.691 | 39.50 ± 0.221 |
*WT indicates wild-type CatA. Others are mutated proteins. Errors (standard deviations) were calculated based on at least three independent experiments.
