ProductMannosyltransferase MgtA
CommentsRv0557, (MTCY25D10.36), len: 378 aa. MgtA (previously known as pimB), mannosyltransferase (see citation below), similar to other various transferases e.g. NP_243554.1|NC_002570 alpha-D-mannose-alpha(1-6)phosphatidyl myo-inositol monomannoside transferase from Bacillus halodurans (381 aa); NP_249533.1|NC_002516 probable glycosyl transferase from Pseudomonas aeruginosa (406 aa); NP_419573.1|NC_002696 glycosyl transferase, group 1 family protein, from Caulobacter crescentus (455 aa); etc. Also similar to Q55598 hypothetical 44.9 kDa protein from synechocystis SP (409 aa), FASTA scores: opt: 703, E(): 0, (33.9% identity in 378 aa overlap); GPI3_YEAST|P32363 n-acetylglucosaminyl-phosphatidylinositol biosynthetic protein (452 aa), FASTA scores: opt: 230, E(): 1.1e-07, (23.5% identity in 328 aa overlap).
Functional categoryLipid metabolism
MutantEssential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). M. tuberculosis Erdman Rv0557 mutant has reduced amounts of lipoarabinomannan (LAM) and lipomannan (LM) and kills human monocyte-derived macrophages at an increased rate (See Torrelles et al., 2009).
