Mutationa | Deamino-NADH oxidase activityb (nmoles/mg protein/min) | % Deamino-NADH oxidase activityc |
---|---|---|
pBA400 | 165±48 (15)c | 100 |
K581C+R99C | 160±12 (2) | 97 |
pBA400-SpeI | 95±8 (5) | 100 |
T292+R99C | 97±8 (2) | 102 |
K581C+R99C was made in the background of pBA400, T292+R99C was made in the background of pBA400-SpeI
Activity was measured in membrane preparations as described in “Methods”. The mean, standard error and (number of measurements) are shown.
Activity is expressed as a percentage of the wild type rate.
