C136A
mutant has 90% of the activity compared to wild type in the presence of Fe(II). As the wild-type enzyme the mutant enzyme requires dithiothreitol for activity
C151S
mutant has 6% of the activity compared to wild type in the presence of Fe(II). When dithiothreitol is present in the reaction the mutant shows 24% of the wild type activity
C229A
mutant has 92% of the activity compared to wild type in the presence of Fe(II)
C71S
mutant has 4% of the activity compared to wild type in the presence of Fe(II). When dithiothreitol is present in the reaction the mutant shows 24% of the wild type activity
E274A
1-2% of wild type activity
H126N
51% of wild type activity, significant alteration in Mn2+ binding
H126N
51% of wild-type activity with Mn2+-activated mutant enzyme. Interaction with the required Mn2+ is significantly altered. Mutation is not accompanied by change in Km-value, Ki-value for putrescine inhibition, molecular weight, tryptophan fluorescence properties or CD spectra of the enzyme
H151N
30% of wild type activity, significant alteration in Mn2+ binding
H151N
30% of wild-type activity with Mn2+-activated mutant enzyme. Interaction with the required Mn2+ is significantly altered. Mutation is not accompanied by change in Km-value, Ki-value for putrescine inhibition, molecular weight, tryptophan fluorescence properties or CD spectra of the enzyme
