Crystal structure of tripartite-type ABC transporter MacB from Acinetobacter baumannii
Abstract
The tripartite multidrug efflux pump MacA-MacB-TolC in Gram-negative bacterial pathogens is driven by the ATPase MacB, which belongs to the ATP-binding cassette (ABC) superfamily. Here the authors present the 3.4 Å resolution crystal structure of MacB, and compare it with other known ABC transporter structures.
