To replicate inside macrophages and cause tuberculosis, Mycobacterium tuberculosis must scavenge a variety of nutrients from the host<sup>1,2</sup>. The mammalian cell entry (MCE) proteins are important virulence factors in M. tuberculosis<sup>1,3</sup>, where they are encoded by large gene clusters and have been implicated in the transport of fatty acids<sup>4-7</sup> and cholesterol<sup>1,4,8</sup> across the impermeable mycobacterial cell envelope. Very little is known about how cargos are tr  ...[more]
