Gene Rv3713
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in cobalamin biosynthesis. Catalyzes amidations at positions B, D, E, and G on adenosylcobyrinic A,C-diamide. NH(2) groups are provided by glutamine, and one molecule of ATP is hydrogenolyzed for each amidation. |
| Product | Possible cobyric acid synthase CobQ2 |
| Comments | Rv3713, (MTV025.061), len: 231 aa. Possible cobQ2, cobyric acid synthase, equivalent to O69521|ML2327|MLCB2407.23c hypothetical 24.5 KDA protein from Mycobacterium leprae (230 aa), FASTA scores: opt: 1313, E(): 4.7e-73, (86.1% identity in 230 aa overlap). Also partially similar to several cobyric acid synthases and hypothetical proteins e.g. Q9FCA0|2SCG58.13 hypothetical 26.2 KDA protein from Streptomyces coelicolor (242 aa), FASTA scores: opt: 639, E(): 6.2e-32, (46.6% identity in 234 aa overlap); Q9ZGG8|COBQ cobyric acid synthase from Heliobacillus mobilis (252 aa), FASTA scores: opt: 501, E(): 1.7e-23, (40.75% identity in 206 aa overlap); BAB58053|SAV1891 hypothetical 27.4 KDA protein from Staphylococcus aureus subsp. aureus Mu50 (243 aa), FASTA scores: opt: 400, E(): 2.3e-17, (35.95% identity in 217 aa overlap); Q9CGJ1|COBQ cobyric acid synthase from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (261 aa), FASTA scores: opt: 353, E(): 1.8e-14, (35.3% identity in 201 aa overlap); O26880|COBQ_METTH|MTH787 probable cobyric acid synthase from Methanobacterium thermoautotrophicum (504 aa), FASTA scores: opt: 201, E(): 5.6e-05, (33.35% identity in 171 aa overlap); etc. Also similar to hypothetical mycobacterial proteins O05811|COBB_MYCTU|Rv2848c|MT2914|MTCY24A1.09 (457 aa) and P71842|Rv0789c|MTCY369.33c (199 aa). Seems to belong to the COBB/COBQ family, COBQ subfamily. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). 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, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
