| Identification |
| Name: |
Respiratory nitrate reductase 1 gamma chain |
| Synonyms: |
- Cytochrome B-NR
- Nitrate reductase A subunit gamma
- Quinol-nitrate oxidoreductase subunit gamma
|
| Gene Name: |
narI |
| Enzyme Class: |
|
| Biological Properties |
| General Function: |
Involved in nitrate reductase activity |
| Specific Function: |
The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The gamma chain is a membrane-embedded heme-iron unit resembling cytochrome b, which transfers electrons from quinones to the beta subunit |
| Cellular Location: |
