In particular, lipoarabinomannan (LAM) has multiple immunomodulatory effects," researchers in London, the United Kingdom report. "In the nonpathogenic species Mycobacterium smegmatis, EmbC has been identified as a key arabinosyltransferase involved in the incorporation of arabinose into LAM, and an embC mutant is viable but lacks LAM.
