General annotation
Gene nameembR
Rv numberRv1267c
FunctionInvolved in transcriptional mechanism. Thought to regulate the biosynthesis of the mycobacterial cell wall arabinan and resistance to ethambutol (EMB; dextro-2,2'-(ethylenediimino)-DI-1-butanol), regulating EMBA|Rv3794 and EMBB|Rv3795.
ProductProbable transcriptional regulatory protein EmbR
CommentsRv1267c, (MT1305, MTCY50.15), len: 388 aa. Probable embR, regulatory protein (see citation below), similar to many e.g. AFSR_STRCO|P25941 regulatory protein AfsR from Streptomyces coelicolor (993 aa), FASTA scores: opt: 489, E(): 1e-25, (33.5% identity in 361 aa overlap); etc. Belongs to the AFSR/DNRI/REDD family of regulators. Phosphorylated in vitro by PknJ|Rv2088 (See Jang et al., 2010).
Molecular mass (Da)41933.5

Functional categoryregulatory proteins

ProteomicsIdentified in the cell membrane 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 30 days but not 90 days (See Kruh et al., 2010). Identified 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).
Mutationnon essential gene by Himar1-based 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 sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website
