FunctionInvolved in transcriptional mechanism and regulates nitrate/nitrite.
ProductPossible nitrate/nitrite response transcriptional regulatory protein NarL
CommentsRv0844c, (MTV043.37c), len: 216 aa. Possible narL, nitrate/nitrite response regulator protein, similar to many e.g. CAB44989.1|AJ131854 NarL protein from Pseudomonas stutzeri (218 aa); CAA75536.1|Y15252 nitrate/nitrite regulatory protein from Pseudomonas aeruginosa (216 aa); PCC6803|D64005|SYCSLRG_24 NarL protein from Synechocystis sp. (209 aa), FASTA scores: opt: 438, E(): 1.5e-23, (34.6% identity in 208 aa overlap); etc. Also similar to unidentified regulator e.g. CAB76009.1|AL157916 putative two-component system response regulator from Streptomyces coelicolor (224 aa); etc. Contains probable helix-turn helix motif from aa 170-191 (Score 1124, +3.02 SD).
Functional categoryRegulatory proteins
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantNon-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). Virulence of M. tuberculosis H37Rv mutant in SCID mice is unchanged (See Parish et al., 2004).
