General annotation
| Type | CDS |
| Function | Function unknown; hydrolyses peptides and/or proteins. |
| Product | Possible protease |
| Comments | Rv3668c, (MTV025.016c), len: 232 aa. Possible protease (and more specifically a putative alkaline serine protease, equivalent to Q9CB98|ML2295 hypothetical protein from Mycobacterium leprae (234 aa), FASTA scores: opt: 1249, E(): 7.4e-66, (77.5% identity in 231 aa overlap). Also similar at C-terminal end with many proteases e.g. O86984 alkaline serine protease precursor from Thermomonospora fusca (368 aa), FASTA scores: opt: 190, E(): 0.00056, (28.9% identity in 173 aa overlap); Q55353|SAPII alkaline serine protease II from Streptomyces sp (382 aa), FASTA scores: opt: 160, E(): 0.032, (27.15% identity in 199 aa overlap); O54109|SC10A5.18 putative secreted protease from Streptomyces coelicolor (411 aa), FASTA scores: opt: 155, E(): 0.066, (26.4% identity in 163 aa overlap); Q54392|SAL|SCI11.35C serine protease SAL precursor (300 aa), FASTA scores: opt: 153, E(): 0.068, (28.1% identity in 185 aa overlap); P00778|PRLA_LYSEN|alpha-LP alpha-LYTIC protease precursor (397 aa), FASTA scores: opt: 154, E(): 0.074, (26.75% identity in 172 aa overlap); etc. Also similar with Q50618|YI15_MYCTU|Rv1815|MT1863|MTCY1A11.28c hypothetical 22.8 KDA protein from Mycobacterium tuberculosis (221 aa), FASTA scores: opt: 134, E(): 0.69, (30.95% identity in 181 aa overlap). 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 | Predicted secreted protein/surface lipoprotein - identified in culture filtrates of M. tuberculosis H37Rv; signal peptide predicted and cleavable signal sequence confirmed experimentally (See Malen et al., 2007). Identified by mass spectrometry in the culture filtrate of M. tuberculosis H37Rv but not the membrane protein fraction or whole cell lysates (See de Souza et al., 2011). |
| 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, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
