Structure of the E418A, Y445A doubly ungated mutant of E.coli CLC_Ec1, Cl-/H+ antiporter
Template:ABSTRACT PUBMED 18678918
Function
[CLCA_ECOLI] 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.[1] [2] [3] [4] [5]
About this Structure
3det is a 6 chain structure with sequence from Escherichia coli and Mus musculus. Full crystallographic information is available from OCA.
