Comments
[?]
| case <OG:Chloroplast> | |
| FUNCTION | May be involved in proton extrusion. Indirectly promotes efficient inorganic carbon uptake into chloroplasts. |
| SUBCELLULAR LOCATION | Plastid, chloroplast inner membrane; Multi-pass membrane protein. |
| else case <OC:Cyanobacteriota> | |
| FUNCTION | Involved in light-induced Na(+)-dependent proton extrusion. Also seems to be involved in CO(2) transport. |
| SUBCELLULAR LOCATION | Cell inner membrane; Multi-pass membrane protein. |
| end case | |
| SIMILARITY | Belongs to the CemA family. |
