Gene Rv3881c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown. Is a proteolytic substrate of MYCP1|Rv3883c. |
| Product | Secreted ESX-1 substrate protein B, EspB. Conserved alanine and glycine rich protein |
| Comments | Rv3881c, (MTV027.16c), len: 460 aa. EspB, ESX-1 substrate protein B (See McLaughlin et al., 2007). Conserved ala-, gly-rich protein. C-terminal end highly similar to O06126 hypothetical 9.5 KDA protein (fragment) from Mycobacterium tuberculosis strain NTI 64719 (90 aa) FASTA scores: opt: 333, E(): 6.3e-07, (69.75% identity in 86 aa overlap) but sequence difference causes frameshift in NTI 64719. Also similar to part of small Mycobacterium leprae ORF O33078|MLCB628.06 (EMBL:Y14967) (101 aa), FASTA scores: opt: 194, E(): 0.04, (59.3% identity in 54 aa overlap), suggesting this is represented by a pseudogene in Mycobacterium leprae. |
| Functional category | Cell wall and cell processes |
| Proteomics | The product of this CDS corresponds to spot 1_607 identified by proteomics at the Max Planck Institute for Infection Biology, Berlin, Germany (See Mattow et al., 2001). Identified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified in the culture filtrate of M. tuberculosis H37Rv using LC-MS/MS; antigen recognized by serum pool from tuberculosis patients (See Malen et al., 2008). 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). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar 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). Disruption of this gene provides a growth advantage 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 |
