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.
