Antibody responses against Mycobacteria infection have been reported, but whether and how they impact anti-bacteria immunity in the host is unclear. Here the authors characterize human anti-Mycobacteria antibodies to find them targeting a Mycobacteria transporter protein, PstS1, show distinct interaction modes in crystal structure, and mediate protection in vitro.
