    1.17.4.1 | C225A |
4-6% of wild-type activity |
437938 |
| 1.17.4.1 | C225S |
C225 appears to be one of the participants in the direct reduction of substrate |
437936 |
| 1.17.4.1 | C225S |
major product formed by interaction with CDP is cytosine |
437938 |
| 1.17.4.1 | C428S |
mutantion is lethal. Cells carrying both the C428S and the SX2S mutation of CX2C motif on plasmids are viable and form colonies with an efficiency similar to that of the wild-type control showing interallelic complementation |
676888 |
| 1.17.4.1 | C439A |
4-6% of wild-type activity |
437938 |
| 1.17.4.1 | C439S |
the C439S mutant of the Escherichia coli R1 is catalytically inactive in vitro |
676888 |
| 1.17.4.1 | C462S |
in the presence of dithiothreitol the major product formed by interaction with CDP is cytosine |
437938 |
| 1.17.4.1 | C754A |
active with dithiothreitol as reductant, 3% of wild type activity with thioredoxin |
437938 |
| 1.17.4.1 | C759A |
active with dithiothreitol as reductant, 3% of wild type activity with thioredoxin |
437938 |
| 1.17.4.1 | C759S |
C759 may play a role in the relay of electrons between thioredoxin and subunit B1 |
