1.1.3.38 | D170A |
only 50% of the FAD is covalently bound. With vanilly alcohol, eugenol, and 4-(methoxymethyl)phenol the mutant enzyme is more than 1000fold less active than the wild-type enzyme |
654161 |
1.1.3.38 | D170A/T457E |
produces (S)-1-(4'-hydroxyphenyl)ethanol from 4-ethylphenol. The wild-type enzyme produces (R)-1-(4'-hydroxyphenyl)ethanol |
654161 |
1.1.3.38 | D170E |
with vanilly alcohol, eugenol, and 4-(methoxymethyl)phenol the mutant enzyme is 5-fold to 100fold less active than the wild-type enzyme |
654161 |
1.1.3.38 | D170N |
no FAD is covalently bound. With vanilly alcohol, eugenol, and 4-(methoxymethyl)phenol the mutant enzyme is more than 1000fold less active than the wild-type enzyme |
654161 |
1.1.3.38 | D170S |
with vanilly alcohol, eugenol, and 4-(methoxymethyl)phenol the mutant enzyme is more than 1000fold less active than the wild-type enzyme |
654161 |
1.1.3.38 | D170S/T457E |
produces (S)-1-(4'-hydroxyphenyl)ethanol from 4-ethylphenol. The wild-type enzyme produces (R)-1-(4'-hydroxyphenyl)ethanol |

1.1.3.38 | D170E |
substrate preference is similar to wild-type enzyme, as the wild-type enzyme the mutant enzyme favors the production of alkenes |
655540 |
1.1.3.38 | D170S |
most active with branched-chain 4-alkylphenol, mutant enzyme favors the formation of alcohols |

1.1.3.38 | H422A |
mutant enzyme retains activity, turnover rates decrease by 1 order of magnitude. Mutant enzyme is still able to form a stable binary complex of reduced enzyme and a quinone methide product intermediate, a crucial step during vanillyl-alcohol oxidase-mediated catalysis. Although mutation prevents covalent linkage of FAD, mutant enzyme contains tightly bound FAD |
655975 |
1.1.3.38 | H422C |
mutant enzyme retains activity, turnover rates decrease by 1 order of magnitude. Although mutation prevents covalent linkage of FAD, mutant enzyme contains tightly bound FAD |
