FunctionMannosyltansferase responsible for the addition of alpha(1->2) branches to the mannan core in the biosynthesis of lipomannan (LM) and lipoarabinomannan (lam)
ProductAlpha(1->2)mannosyltransferase
CommentsRv2181, (MTV021.14), len: 427 aa. Alpha(1->2)mannosyltransferase (See Kaur et al., 2006). Probable integral membrane protein, similar to others in Mycobacterium tuberculosis e.g. Rv1159 (MTCI65.26, 431 aa). Start uncertain. FASTA scores: Z95584|MTCI65_26 (431 aa) opt: 428, E(): 8e-22; 31.2% identity in 407 aa overlap. Predicted to be in the GT-C superfamily of glycosyltransferases (See Liu and Mushegian, 2003).
Functional categoryCell wall and cell processes
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene provides a growth advantage for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
