Gene Rv1963c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in transcriptional mechanism; repression of the MCE3 operon. Could also have a regulatory action on the MCE2 operon. |
| Product | Probable transcriptional repressor (probably TetR-family) Mce3R |
| Comments | Rv1963c, (MTV051.01c-MTCY09F9.01), len: 406 aa. Probable mce3R, negative transcriptional regulatory protein, TetR family (see citation below); similar to several transcriptional regulator e.g. AL049485|SC6A5.30 Streptomyces coelicolor cosmid 6 a (404 aa), FASTA scores: opt: 319, E(): 6.4e-13, (29.5% identity in 373 aa overlap); and Z84498|MTCY9F9_1 (259 aa), FASTA scores: opt: 208, E(): 1.6e-07, (100.0% identity in 32 aa overlap). Contains probable helix-turn-helix at aa 36-57 (+4.23 SD) and two tet-R family signatures. |
| Functional category | Regulatory proteins |
| Mutant | Non-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). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv on cholesterol, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Growth of M. tuberculosis H37Rv mce3R|Rv1963c mutant in vitro and in J774 murine macrophages is comparable to wild-type (See Santangelo et al., 2008; Santangelo et al., 2009); TLC shows some lipids are missing from mutant (See Santangelo et al., 2009).
