Abstract:The type I adenosine 5′-triphosphate (ATP)–binding cassette (ABC) transporter DppABCD is believed to be responsible for the import of exogenous heme as an iron source into the cytoplasm of the human pathogen
Mycobacterium tuberculosis
(
Mtb
). Additionally, this system is also known to be involved in the acquisition of tri- or tetra-peptides. Here, we report the cryo–electron microscopy structures of the dual-function
