Gene Rv0890c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in transcriptional mechanism. |
| Product | Probable transcriptional regulatory protein (probably LuxR-family) |
| Comments | Rv0890c, (MTCY31.18c), len: 882 aa. Probable transcriptional regulatory protein, LuxR family, highly similar (but shorter 238 aa in N-terminus) to NP_302202.1|NC_002677 possible transcriptional regulator from Mycobacterium leprae (1106 aa). Also highly similar (generally in part) to others e.g. T50568 probable multi-domain regulatory protein from Streptomyces coelicolor (1334 aa); P10957|NARL_ECOLI nitrate/nitrite response regulator protein from Escherichia coli (216 aa), FASTA scores: opt: 193, E(): 6e-06, (37.4% identity in 99 aa overlap); etc. Also highly similar to others from Mycobacterium tuberculosis e.g. MTCY02B10_22, MTV008_44, MTV036_21, and MTCY31_24. Contains PS00017 ATP/GTP-binding site motif A (P-loop), PS00622 Bacterial regulatory proteins, luxR family signature, and probable helix-turn helix motif from aa 836 to 857 (Score 1559, +4.50 SD). Belongs to the LuxR/UhpA family of transcriptional regulators. Alternative nucleotide at position 990001 (G->C; P866A) has been observed. |
| Functional category | Regulatory proteins |
| Proteomics | Identified in the cytosol and cell wall fraction 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 90 days but not 30 days (See Kruh et al., 2010). Translational start site supported by proteomics data (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). 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). 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 |
