CC -!- FUNCTION: Involved in the initiation of core alpha-(1->6) mannan
CC biosynthesis of lipomannan (LM-A) and multi-mannosylated polymer (LM-
CC B), extending triacylatedphosphatidyl-myo-inositol dimannoside
CC (Ac1PIM2) and mannosylated glycolipid, 1,2-di-O-C16/C18:1-(alpha-D-
CC mannopyranosyl)-(1->4)-(alpha-D-glucopyranosyluronic acid)-(1->3)-
CC glycerol (Man1GlcAGroAc2), respectively. Catalyzes the addition of
CC alpha-(1->6)-mannose residue. {ECO:0000269|PubMed:18452585}.
CC -!- PATHWAY: Cell wall biogenesis; cell wall polysaccharide biosynthesis.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305|PubMed:18452585}; Multi-
CC pass membrane protein {ECO:0000305}.
CC -!- DISRUPTION PHENOTYPE: Cells lacking this gene are unable to synthesize
CC lipoglycans (LM-A, LM-B and lipoarabinomannan (LAM)).
CC {ECO:0000269|PubMed:18452585}.
CC -!- SIMILARITY: Belongs to the MptA/B family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAB98959.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
