LITERATURE
30-50% loss of activity by repeated freezing and thawing
-
enzyme is rapidly denatured by even micromolar concentrations of ferricyanide
-
total enzyme activity is significantly decreased by ammonium sulfate precipitation, leaving 20% of the initial activity in the supernatant
F6KEW4; F6KEW3
unstable to air with a half-life of 12 min, the 4Fe-4S cluster is converted into a 2Fe-2S form
