Gene Rv1338
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in peptidoglycan biosynthesis. Provides the (R)-glutamic acid required for cell wall biosynthesis [catalytic activity: L-glutamate = D-glutamate] |
| Product | Probable glutamate racemase MurI |
| Comments | Rv1338, (MTCY130.23), len: 271 aa. Probable murI, glutamate racemase, highly similar to many e.g. MURI_MYCLE|P46705 (272 aa), FASTA scores: opt: 1559, E(): 0, (88.9% identity in 271 aa overlap). Contains PS00924 Aspartate and glutamate racemases signature 2. |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
