Gene Rv1223 (degP)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Possibly hydrolyzes peptides and/or proteins (seems to cleave preferentially after serine residue). |
| Product | Probable serine protease HtrA (DEGP protein) |
| Comments | Rv1223, (MTCI61.06), len: 528 aa. Probable htrA (alternate gene name: degP), serine protease precursor (see citations below), equivalent to U15180|MLU15180_31|Q49972|ML1078|HTRA possible serine protease from Mycobacterium leprae (533 aa), FASTA scores: opt: 2777, E(): 4.1e-141, (81.6% identity in 533 aa overlap). Also similar to many others e.g. HTRA_ECOLI|P09376 protease do precursor from Escherichia coli (474 aa), FASTA scores: opt: 581, E(): 9.1e-27, (36.3% identity in 278 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop). Start changed since first submission (-21 aa). 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 cell membrane fraction 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 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 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (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). 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).
