Comments [?]

case <OC:Enterobacterales>
Function Probably acts as an electrical shunt for an outwardly-directed proton pump that is linked to amino acid decarboxylation, as part of the extreme acid resistance (XAR) response.
end case
case not defined <Property:Membrane> or <Property:Membrane=1>
Subcellular location Cell membrane; Multi-pass membrane protein.
else case <Property:Membrane=2>
Subcellular location Cell inner membrane; Multi-pass membrane protein.
end case
Similarity Belongs to the chloride channel (TC 2.A.49) family. ClcB subfamily.

Keywords [?]

case defined <Property:Membrane> and <Property:Membrane=2>
end case

Comments In view of recent findings for ClcA in E.coli, ClcB may also be an exchange transporter and not a voltage-gated channel.
