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. |

Comments | The amino-terminus is very variable. A number of organisms have inserts; CHLRE, LEPTE, SCEOB, STAPU, STIHE and have therefore been made atypical. |
