LITERATURE
C202A
site-directed mutagenesis
H211A
site-directed mutagenesis, the mutant shows moderate uncoupling of their rates of NAD+ and 2,5-DHP product formation, suggesting that the variant has lost some efficiency in hydroxylating the substrate
H302A
site-directed mutagenesis, the mutant shows moderate uncoupling of their rates of NAD+ and 2,5-DHP product formation, suggesting that the variant has lost some efficiency in hydroxylating the substrate
H47A
site-directed mutagenesis, inactive mutant, unable to bind FAD
H47E
site-directed mutagenesis, the mutant can bind FAD, but shows very low activity compared to wild-type. The mutant shows significant consequences in its hydroxylating activity, with NADH oxidization proceeding much more rapidly than 6-HNA is decarboxylated and hydroxylated
H47F
site-directed mutagenesis, inactive mutant, unable to bind FAD
Y215F
site-directed mutagenesis, the mutant shows significant consequences in its hydroxylating activity, with NADH oxidization proceeding much more rapidly than 6-HNA is decarboxylated and hydroxylated
Y225F
site-directed mutagenesis, the mutant shows moderate uncoupling of their rates of NAD+ and 2,5-DHP product formation, suggesting that the variant has lost some efficiency in hydroxylating the substrate
