Gene Rv2922c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Plays an important role in chromosome structure and partitioning. Essential for chromosome partition. |
| Product | Probable chromosome partition protein Smc |
| Comments | Rv2922c, (MT2990, MTCY338.11c), len: 1205 aa. Probable smc, chromosome partition protein (ala-, arg-, leu-, glu-rich protein, possibly coiled-coil protein) (see * below), equivalent (but longer 84 aa) to Q9CBT5|SMC|ML1629|MLCB250.01 possible cell division protein from Mycobacterium leprae (1203 aa), FASTA scores: opt: 5957, E(): 0, (79.15% identity in 1205 aa overlap). Also highly similar to other chromosome segregation proteins e.g. Q9ZBQ2|SC7A1.21 putative chromosome associated protein from Streptomyces coelicolor (1186 aa), FASTA scores: opt: 2633, E(): 4.1e-120, (53.03% identity in 1205 aa overlap); P51834|SMC_BACSU chromosome partition protein from Bacillus subtilis (1186 aa), FASTA scores: opt: 1009, E(): 2.1e-41, (30.75% identity in 1205 aa overlap); Q9CHC9|SMC chromosome segregation protein from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (924 aa), FASTA scores: opt: 996, E(): 7.5e-41, (29.75% identity in 874 aa overlap); etc. Equivalent to AAK47317 from Mycobacterium tuberculosis strain CDC1551 (1205 aa) but longer 84 aa. Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the SMC family. N-terminus shortened since first submission. [* Note: Unpublished.

| Functional category | Cell wall and cell processes |
| Proteomics | Identified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (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). Check for mutants available at TARGET website |
