Method: Electron Microscopy, Resolution 3.23Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function MMPL3_MYCS2 Transports trehalose monomycolate (TMM) to the cell wall (PubMed:31239378, PubMed:22520756, PubMed:28698380). Flips TMM across the inner membrane. Membrane potential is not required for this function (PubMed:28698380). Transports probably phosphatidylethanolamine (PE) as well. Binds specifically both TMM and PE, but not trehalose dimycolate (TDM). Binds also diacylglycerol (DAG) and other phospholipids, including phosphatidylglycerol (PG), phosphatidylinositol (PI), and cardiolipin (CDL) (PubMed:31113875). Contributes to membrane potential, cell wall composition, antibiotic susceptibility and fitness (PubMed:28703701).
