ProductProbable transcriptional regulatory protein LrpA (Lrp/AsnC-family)
CommentsRv3291c, (MTCY71.31c), len: 150 aa. Probable lrpA, transcriptional regulator Lrp/AsnC-family, similar to other regulatory proteins e.g. Q9RKY4|SC6D7.14 from Streptomyces coelicolor (165 aa), FASTA scores: opt: 503, E(): 9.1e-26, (50.35% identity in 143 aa overlap); Q9KYP0|SCD69.13 from Streptomyces coelicolor (167 aa), FASTA scores: opt: 310, E(): 2.7e-13, (37.2% identity in 129 aa overlap); BAB50701|MLL3910 from Rhizobium loti (Mesorhizobium loti) (152 aa), FASTA scores: opt: 282, E(): 1.6e-11, (39.55% identity in 129 aa overlap); O87635|LRP_KLEAE from Klebsiella aerogenes (163 aa), FASTA scores: opt: 279, E(): 2.5e-11, (38.1% identity in 147 aa overlap); etc. Contains helix-turn-helix motif at aa 22-43 (+3.94 SD). Could belong to the Lrp/AsnC family of transcriptional regulators.
Functional categoryRegulatory proteins
ProteomicsIdentified 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). Translational start site supported by proteomics data (See de Souza et al., 2011).
TranscriptomicsmRNA identified by microarray analysis and up-regulated after 4h, 24h and 96h of starvation (see citation below).
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 strain (see Sassetti et al., 2003).
