Gene Rv2850c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown; possibly introduces a magnesium ion into specific substrate/compound. |
| Product | Possible magnesium chelatase |
| Comments | Rv2850c, (MTCY24A1.07), len: 629 aa. Possible magnesium-chelatase, highly similar (but with gaps) to magnesium-chelatases from notably photosynthetic organisms involved in chlorophyll biosynthesis e.g. Q9RJ18|SCI8.35c putative chelatase from Streptomyces coelicolor (672 aa), FASTA scores: opt: 1941, E(): 2.1e-85, (54.65% identity in 675 aa overlap); Q9HZQ5|PA2942 probable magnesium chelatase from Pseudomonas aeruginosa (338 aa), FASTA scores: opt: 991, E(): 2.7e-40, (49.45% identity in 368 aa overlap); O33549|BCHI mg protoporphyrin IX chelatase subunit from Rhodobacter sphaeroides (Rhodopseudomonas sphaeroides) (334 aa), FASTA scores: opt: 833, E(): 9.4e-33, (50.65% identity in 318 aa overlap); O30819|BCHI_RHOSH magnesium-chelatase 38 KDA subunit from Rhodobacter sphaeroides (Rhodopseudomonas sphaeroides) (334 aa), FASTA scores: opt: 828, E(): 1.6e-32, (50.3% identity in 318 aa overlap); etc. Equivalent to AAK47242 from Mycobacterium tuberculosis strain CDC1551 (610 aa) but longer 19 aa. COULB belong to the mg-chelatase subunits D/I family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | 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). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| 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). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website |
