LITERATURE
5 - 10
-
bimodal, pH 5: 90% of maximal activity, pH 6.5: about 50% of maximal activity, pH 10: about 70% of maximal activity
5 - 8.6
-
the pH curve is bimodal, with maximal activity exhibited at pH 8.6, a minimum at pH 6.0. and a second maximum at pH 5.0
6.8 - 8.1
-
over 50% of maximal activity within this range
7 - 8.6
at pH 7.0, 7.2, and 8.0, the enzyme activity levels in 100 mM phosphate buffer are approx. 50.2, 88.1, and 81.1%, respectively, relative to that at pH 7.5. HcbA3C-His shows the highest flavin reductase activity in 60 mM KPi buffer
