Function
MMPLB_MYCTU Part of a heme-iron acquisition system. Receives heme from the heme-binding protein Rv0203 and transports it into the mycobacterial cell. Contributes to virulence.[1] [2] [3] Could also transport the mycolic acid-containing lipids monomeromycolyl diacylglycerol (MMDAG) and mycolate ester wax (WE) to the bacterial surface.[4]
