Protein
Probable triacylglyceride transporter MSMEG_3069/MSMEI_2992
Organism
Mycobacterium smegmatis (strain ATCC 700084 / mc(2)155)
Function
In association with lipoprotein LprG probably transports triacyglycerides (TAG) across the inner cell membrane into the periplasm; TAG probably regulates lipid metabolism and growth regulation (By similarity). Confers resistance to ethidium bromide, possibly acting as an efflux pump, requires LprG lipoprotein for normal function (PubMed:18156250). Export of ethidium bromide can be complemented by the equivalent operon from M.tuberculosis (lprG-Rv1410c) (PubMed:18156250).
Similarity
Belongs to the major facilitator superfamily.
