A FocA variant incapable of formate import but retaining formic acid efflux highlights the distinct mechanisms governing bidirectional formate translocation
{{output}}
FocA belongs to the formate-nitrite transporter (FNT) superfamily of pentameric membrane proteins, which translocate small, monovalent anions across the cytoplasmic membrane of bacteria, archaea and certain protists. FocA translocates formate anions or formic ... ...
