MmpL3 Transporter (MmpL3)

Target
MmpL3
Molecular classification
Transporter, Membrane protein, RND family transporter
01

Overview

MmpL3 is an essential inner membrane transporter in Mycobacterium tuberculosis responsible for exporting trehalose monomycolate (TMM). TMM is a precursor for mycolic acid synthesis, a crucial component of the mycobacterial cell wall. MmpL3 functions as a proton motive force-dependent antiporter, coupling inward proton movement with outward TMM transport. Inhibition of MmpL3 disrupts cell wall biosynthesis, leading to bacterial death, making it an attractive drug target for tuberculosis.
