| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). Identified in both the aqueous and detergent phases of Triton X-114 extracts of M. tuberculosis H37Rv membranes using 1-DGE, CEGE, and MALDI-TOF-MS (See Sinha et al., 2005). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). 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). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
