Engineered MATE multidrug transporters reveal two functionally distinct ion-coupling pathways in NorM from Vibrio cholerae
Raturi and Nair et al. describe functional ion pathways within the MATE transporter NorM from Vibrio cholerae (NorM-VC). By creating chimeric proteins and mutants of NorM-VC and NorM-PS, they dissect the localisation of ion-coupling events and roles of conserved catalytic carboxylates in H+ binding...

| Sumario: | Raturi and Nair et al. describe functional ion pathways within the MATE transporter NorM from Vibrio cholerae (NorM-VC). By creating chimeric proteins and mutants of NorM-VC and NorM-PS, they dissect the localisation of ion-coupling events and roles of conserved catalytic carboxylates in H+ binding and Na+ coordination, with findings useful to the field of transporters and drug resistance pumps. |
