Note that it has been shown hmp transcription increased at early stationary phase and is lower at late stationary phase and during exponential growth. Note that previously known as hmp. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified 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 of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by Northern blotting analysis (induction in response to oxygen limitation, nitrosative and oxidative stress) (see citation below). |
| Mutant | Non-essential 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). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). M. tuberculosis H37Rv kshB|Rv3571 mutant shows in vitro growth defect with cholesterol, 5-alpha-androstane-3,17-dione, 4-androstene-3,17-dione as carbon source; mutant shows growth defect in BALB/c mice and in resting and activated J774A.1 and BALB/c bone marrow-derived macrophages; SCID mice infected with mutant survive longer than those infected with wild-type; mutant cell wall is altered (See Hu et al., 2010).
