ProductESX conserved component EccB3. ESX-3 type VII secretion system protein. Possible membrane protein.
CommentsRv0283, (MTV035.11), len: 538 aa. eccB3, esx conserved component, ESX-3 type VII secretion system protein, possible membrane protein, similar to several hypothetical mycobacterial proteins e.g. Z94121|MTY15F10_16|Rv3895c from Mycobacterium tuberculosis (495 aa), FASTA scores: opt: 698, E(): 0, (37.6% identity in 492 aa overlap); Rv1782; Rv3450c; Rv3869; and Y14967|MLCB628_16|MLCB628.17c from Mycobacterium leprae (481 aa), FASTA scores: opt: 672, E(): 1.5e-31, (37.2% identity in 506 aa overlap). Contains PS00017 ATP/GTP-binding site motif A (P-loop). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).
Functional categoryCell wall and cell processes
ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS; predicted transmembrane protein (See Gu et al., 2003). Identified in the cell wall and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS; predicted integral membrane protein (See Xiong et al., 2005). Identified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). 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 and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
TranscriptomicsmRNA identified by microarray analysis and down-regulated after 24h and 96h of starvation (see citation below). DNA microarrays indicate repression by iron and IdeR|Rv2711 in M. tuberculosis H37Rv (See Rodriguez et al., 2002).
MutantEssential 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 by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
