Gene Rv1796
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Thought to have proteolytic activity. |
| Product | Probable proline rich membrane-anchored mycosin MycP5 (serine protease) (subtilisin-like protease) (subtilase-like) (mycosin-5) |
| Comments | Rv1796, (MTV049.18), len: 585 aa. Probable mycP5, pro-rich membrane-anchored serine protease (mycosin) (see citations below). Member of family with four other Mycobacterium tuberculosis serine proteases: Rv3886c|O05458|MTCY15F10.26|Z94121 (550 aa), FASTA scores: opt: 1173, E(): 0, (47.9% identity in 578 aa overlap); Rv0291, Rv3883c, and Rv3449. Genes all linked to those of ESAT-6 family. Has possible N-terminal signal peptide and hydrophobic anchor-like stretch at C-terminus. Contains two serine protease, subtilase family active site motifs: a aspartic acid active site motif (PS00136); and a histidine active site motif (PS00137). Belongs to peptidase family S8 (also known as the subtilase family), pyrolysin subfamily. Conserved in M. tuberculosis, M. leprae, M. bovis and M. avium paratuberculosis; predicted to be essential for in vivo survival and pathogenicity (See Ribeiro-Guimaraes and Pessolani, 2007). |
| 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 M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh 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). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene results in growth defect of H37Rv in vitro, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Check for mutants available at TARGET website |
