ProductPossible transcriptional regulatory protein
CommentsRv0823c, (MTV043.15c), len: 389 aa. Possible transcriptional regulator (resembles nitrogen regulation protein), equivalent (but longer 24 aa in N-terminus) to MLU15182_31|U15182|NtrB NtrB protein from Mycobacterium leprae (384 aa), FASTA scores: opt: 2070, E(): 0, (82.3% identity in 384 aa overlap) (see citation below). Also highly similar to CAB63312.1|AL133471|SCC82.03c hypothetical protein from Streptomyces coelicolor (406 aa); and to many transcriptional regulators members of UPF0034 family (NIFR3/SMM1) e.g. D26185|BAC180K_143 protein similar to transcriptional regulator (nitrogen regulation protein) from Bacillus subtilis (333 aa), FASTA scores: opt: 609, E(): 1.4e-32, (38.3% identity in 326 aa overlap); NP_349795.1|NC_003030 NifR3 family enzyme from Clostridium acetobutylicum (321 aa); etc. Contains PS01136 Uncharacterized protein family UPF0034 signature.
Functional categoryRegulatory proteins
ProteomicsIdentified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010).
MutantDisruption 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 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).
