Comments [?]

case <OG:Chloroplast>
FUNCTIONMay be involved in proton extrusion. Indirectly promotes efficient inorganic carbon uptake into chloroplasts.
SUBCELLULAR LOCATIONPlastid, chloroplast inner membrane; Multi-pass membrane protein.
else case <OC:Cyanobacteriota>
FUNCTIONInvolved in light-induced Na(+)-dependent proton extrusion. Also seems to be involved in CO(2) transport.
SUBCELLULAR LOCATIONCell inner membrane; Multi-pass membrane protein.
end case
SIMILARITYBelongs to the CemA family.
