Probable mycP4, membrane-anchored serine protease (mycosin) (see citation below), similar to hypothetical unknowns or proteases from Mycobacterium tuberculosis strains H37Rv and CDC1551 e.g. AAK48366|MT3998 subtilase family protein from Mycobacterium tuberculosis strain CDC1551 (411 aa), FASTA scores: opt: 747, E(): 3.5e-33, (45.65% identity in 416 aa overlap); O05461|Rv3883c|MTCY15F10.29 membrane-anchored mycosin MYCP1 (446 aa), FASTA scores: opt: 747, E(): 3.8e-33, (45.45% identity in 451 aa overlap); O53695|Rv0291|MTV035.19 probable membrane-anchored mycosin MYCP2 (461 aa), FASTA scores: opt: 660, E(): 1.9e-28, (44.0% identity in 457 aa overlap); etc. And similar to hypothetical proteases from Mycobacterium leprae e.g. O33076|MLCB628.04|ML0041 hypothetical 45.7 KDA protein (probable secreted protease) (446 aa), FASTA scores: opt: 683, E(): 1.1e-29, (43.8% identity in 450 aa overlap); Q9CD36|ML2528 putative protease (475 aa), FASTA scores: opt: 608, E(): 1.3e-25, (43.0% identity in 451 aa overlap); Q9CBV3|ML1538 possible protease (567 aa), FASTA scores: opt: 389, E(): 9.7e-14, (33.8% identity in 562 aa overlap); etc. Also some similarity to other proteases from several organisms e.g. O31788|APRX alkaline serine protease from Bacillus subtilis (442 aa), FASTA scores: opt: 296, E(): 8.3e-09, (29.4% identity in 313 aa overlap); O86650|SC3C3.17c putative secreted serine protease from Streptomyces coelicolor (450 aa), FASTA scores: opt: 279, E(): 7e-08, (33.55% identity in 343 aa overlap); Q9KBJ7|APRX|BH193 intracellular alkaline serine protease from Bacillus halodurans (444 aa), FASTA scores: opt: 257, E(): 1.1e-06, (28.65% identity in 335 aa overlap); O86642|SC3C3.08 serine protease from Streptomyces coelicolor (413 aa), FASTA scores: opt: 243, E(): 5.7e-06, (38.25% identity in 387 aa overlap); etc. Has putative signal peptide at N-terminus and hydrophobic stretch at C-terminus. Contains three signatures typical of subtilase family: aspartic acid active site (PS00136), histidine active site (PS00137), and serine active site (PS00138). Belongs to peptidase family S8 (also known as the subtilase family), pyrolysin subfamily. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). |
| 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 strain (see Sassetti 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 |
