Gene Rv0983 (mtb32b)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown; possibly hydrolyzes peptides and/or proteins (seems to cleave preferentially after serine residues). |
| Product | Probable serine protease PepD (serine proteinase) (MTB32B) |
| Comments | Rv0983, (MTV044.11), len: 464 aa. Probable pepD (alternate gene name: mtb32b), secreted or membrane serine protease (see citation below), equivalent (but longer 18 aa in N-terminus) to AL035500|MLCL373_17|T45448 probable serine proteinase from Mycobacterium leprae (452 aa), FASTA score: (74.2% identity in 466 aa overlap); and highly similar to others from Mycobacterium leprae. Also highly similar (except in N-terminus) to other proteases e.g. CAC01350.1|AL390975 putative protease from Streptomyces coelicolor (542 aa); NP_440705.1|NC_000911|HtrA serine protease from Synechocystis sp. (452 aa); NP_346646.1|NC_003028 serine protease from Streptococcus pneumoniae (393 aa); etc. Also similar in part to members of the htrA-antigen family e.g. U87242|MTU87242_3|HtrA serine protease from M. tuberculosis (542 aa), FASTA scores: opt: 846, E(): 2e-28, (40.6% identity in 392 aa overlap); and similar to other hypothetical serine proteases e.g. Rv0983, Rv0125, etc. Belongs to the serine protease family. 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 in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate and membrane protein fraction of M. tuberculosis H37Rv but not whole cell lysates (See de Souza et al., 2011). |
| Transcriptomics | DNA microarrays detect expression in M. tuberculosis H37Rv in vivo (in BALB/c and SCID mice) but not in vitro (in 7H9 medium) (See Talaat et al., 2004). |
| 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 for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
