General annotation
Gene nametcrX
Rv numberRv3765c
FunctionSensor part of a two component regulatory system.
ProductProbable two component transcriptional regulatory protein TcrX
CommentsRv3765c, (MTV025.113c), len: 234 aa. Probable tcrX, response regulator of a two-component regulatory system, highly similar to others e.g. Q9ADN7|2SC10A7.24 putative two component system response regulator from Streptomyces coelicolor (271 aa), FASTA scores: opt: 1111, E(): 4.8e-63, (72.3% identity in 231 aa overlap); Q9F161 response regulator from Corynebacterium glutamicum (Brevibacterium flavum) (232 aa), FASTA scores: opt: 692, E(): 1.2e-36, (46.0% identity in 226 aa overlap); Q9KZU5|SCD84.23c putative two-component systen response regulator from Streptomyces coelicolor (248 aa), FASTA scores: opt: 674, E(): 1.7e-35, (44.05% identity in 236 aa overlap); etc. Also highly similar to others from Mycobacterium tuberculosis e.g. Q50806|Rv1033c|MTCY10G2.16 response regulator homolog (257 aa), FASTA scores: opt: 947, E(): 1e-52, (59.5% identity in 232 aa overlap); P71814|Rv0757|MTCY369.02 PHOP-like protein (247 aa) FASTA scores: opt: 829, E(): 2.8e-45, (54.65% identity in 225 aa overlap); O53894|Rv0981|MTV044.09 (230 aa), FASTA scores: opt: 662, E(): 9e-35, (44.65% identity in 224 aa overlap); and also similar to MTCY31_34; MTCY19H5_20; MTY13628_5; MTCY20G9_17; and to MLCB57_27 from Mycobacterium leprae; and MBY13627_3 from Mycobacterium bovis BCG. Equivalent to AAK48236 from Mycobacterium tuberculosis strain CDC1551 (286 aa) but shorter 52 aa. The N-terminal region is similar to that of other regulatory components of sensory transduction systems. Similar to bacterial regulatory proteins involved in signal transduction.

Functional categoryregulatory proteins

Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Found to be deleted (partially or completely) in one or more clinical isolates (See Tsolaki et al., 2004). M. tuberculosis H37Rv tcrXY mutant shows increased virulence in SCID mice (See Parish et al., 2004).
