| 1. | Novel nitrite reductases have been isolated from strains of this species.
|
| 2. | Most oxidases and reductases are proton pumps, but some are not.
|
| 3. | Class III reductases are distributed in archaebacteria, eubacteria, and bacteriophages.
|
| 4. | Trypanothione-dependent enzymes include reductases, peroxidases, glyoxalases and transferases.
|
| 5. | It is also used in biochemical experiments as an inhibitor of reductases.
|
| 6. | This flexibility is possible because different oxidases and reductases use the same ubiquinone pool.
|
| 7. | Class I reductases are divided into IA and IB due to differences in regulation.
|
| 8. | Siroheme is a co-factor of both assimilatory and dissimilatory nitrite and sulfite reductases.
|
| 9. | Most of the photosynthetic bacteria have both light-dependent and light-independent reductases.
|
| 10. | Class IA reductases are distributed in eukaryotes, S-adenosyl methionine and an iron sulphur center.
