Tripartite ATP-independent periplasmic (TRAP) transporters use an extra substrate binding protein to transport a variety of substrates in bacteria and archaea. Here the authors use a disulfide engineering approach to lock the TRAP transporter HiSiaPQM from H. influenzae in different conformational states for characterisation.
