Gene Rv3391
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown; involved in cellular metabolism |
| Product | Possible multi-functional enzyme with acyl-CoA-reductase activity AcrA1 |
| Comments | Rv3391, (MTV004.49), len: 650 aa. Possible acrA1, multi functional protein with fatty acyl-CoA reductase activity in C-terminal part. Indeed C-terminal part highly similar to P94129|ACR1 fatty acyl-CoA reductase from Acinetobacter calcoaceticus (295 aa), FASTA scores: opt: 767, E(): 1.4e-36, (45.4% identity in 260 aa overlap); and similar to other oxidoreductases dehydrogenases/reductases e.g. Q9Y3A1 CGI-93 protein (similarity with SDR family) from Homo sapiens (Human) (291 aa), FASTA scores: opt: 363, E(): 1.5e-13, (38.65% identity in 194 aa overlap); Q9L146|SC6D11.09 putative oxidoreductase (similarity with SDR family) from Streptomyces coelicolor (343 aa), FASTA scores: opt: 346, E(): 1.6e-12, (30.4% identity in 283 aa overlap); Q9HSR4|YUSZ1|VNG0115G oxidoreductase from Halobacterium sp. strain NRC-1 (260 aa), FASTA scores: opt: 338, E(): 3.7e-12, (33.85% identity in 248 aa overlap); etc. C-terminus also similar to Mycobacterium tuberculosis proteins Q10783|YF43_MYCTU|Rv1543|MTCY48.22c putative oxidoreductase (341 aa), FASTA scores: opt: 787, E(): 1.2e-37, (39.8% identity in 319 aa overlap); O06413|Rv0547c|MTCY25D10.26c hypothetical 31.8 KDA protein (294 aa), FASTA scores: opt: 565, E(): 4.7e-25, (36.8% identity in 242 aa overlap); O53398|Rv1050|MTV017.03 oxidoreductase (SDR family) (301 aa), FASTA scores: opt: 436, E(): 1.1e-17, (32.2% identity in 292 aa overlap). N-terminus (aa 1-320) is similar to P37693|HETM_ANASP polyketide synthase hetM from Anabaena sp. (506 aa), FASTA scores: opt: 188, E(): 1.3e-07, (27.7% identity in 361 aa overlap); so certainly a multi-domain enzyme. Seems to belong to the short-chain dehydrogenases/reductases (SDR) family. Note that this ORF corresponds to the gene ORF2|Q11197 (see Yuan et al., 1995), but longer 266 aa, due to use of a more upstream start site. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Transcriptomics | mRNA identified by microarray analysis and up-regulated after 96h of starvation (see Betts et al., 2002). |
| 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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
