Canmetcon
Identification
Name:H(+)/Cl(-) exchange transporter ClcA
Synonyms:Not Available
Gene Name:clcA
Enzyme Class:Not Available
Biological Properties
General Function:Involved in ion channel activity
Specific Function:Proton-coupled chloride transporter. Functions as antiport system and exchanges two chloride ions for 1 proton. 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
Cellular Location:Cell inner membrane; Multi-pass membrane protein
