|
|
||
| UniProt code: P07173. |
|
||
| Organism: | |
Blastochloris viridis (Rhodopseudomonas viridis). |
| Taxonomy: | |
Bacteria; Proteobacteria; Alphaproteobacteria; Rhizobiales; Hyphomicrobiaceae; Blastochloris. |
|
||
|
||
| Function: | |
The reaction center of purple bacteria contains a tightly bound cytochrome molecule which re-reduces the photo oxidized primary electron donor. {ECO:0000269|PubMed:10736158}. |
|

| Biophysicochemical properties: | |
Redox potential: E(0) is -60 mV for heme 1. E(0) is +320 mV for heme 2. E(0) is +380 mV for heme 3. E(0) is +15 mV for heme 4. {ECO:0000269|PubMed:10736158}; |
| Subunit: | |
Component of the photosynthetic reaction center composed of protein subunits L (PufL), M (PufM), H (PuhA) and cytochrome C (PufC). {ECO:0000269|PubMed:10024457, ECO:0000269|PubMed:22054235, ECO:0000269|PubMed:6392571, ECO:0000269|PubMed:9351808, ECO:0000269|Ref.7}. |
| Subcellular location: | |
Cellular chromatophore membrane {ECO:0000269|PubMed:10024457, ECO:0000269|PubMed:9351808}; Lipid-anchor {ECO:0000269|PubMed:22054235, ECO:0000269|Ref.4}. |
| Ptm: | |
Binds 4 heme groups per subunit. {ECO:0000269|PubMed:10024457, ECO:0000269|PubMed:10736158, ECO:0000269|PubMed:22054235, ECO:0000269|PubMed:6392571, ECO:0000269|PubMed:9351808, ECO:0000269|Ref.7}. |
| Ptm: | |
After the signal sequence is removed, the N-terminal cysteine is modified to form a diacylglyceride thioether, but the alpha-amino group is free and is not N-palmitoylated. {ECO:0000269|PubMed:22054235, ECO:0000269|Ref.4}. |
| Disruption phenotype: | |
Lack of photosynthesis. {ECO:0000269|PubMed:10736158}. |
