Gene Rv3106
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Generates oxidized ferredoxin from ferredoxin [catalytic activity: reduced ferredoxin + NADP(+) = oxidized ferredoxin + NADPH]. |
| Product | NADPH:adrenodoxin oxidoreductase FprA (NADPH-ferredoxin reductase) |
| Comments | Rv3106, (MTCY164.16), len: 456 aa. FprA, NADPH:adrenodoxin oxidoreductase (NADPH-ferredoxin reductase) (see citations below), equivalent to O32886|MLCB1779.25|FPRA|ML0666 from Mycobacterium leprae (456 aa), FASTA scores: opt: 2505, E(): 1.2e-142, (81,05% identity in 459 aa overlap); also similar to other NADPH:adrenodoxin oxidoreductases e.g. Q9RX19|DR0496 from Deinococcus radiodurans (479 aa), FASTA scores: opt: 1331, E(): 2.6e-72, (48.9% identity in 454 aa overlap); Q9RK35|SCF15.02 from Streptomyces coelicolor (454 aa), FASTA scores: opt: 1102, E(): 1.3e-58, (41.35% identity in 462 aa overlap); P82861 from Salvelinus fontinalis (Brook trout) (498 aa), FASTA scores: opt: 827, E(): 4e-42, (41.3% identity in 460 aa overlap); Q9V3T9|ADRO_DROME from Drosophila melanogaster (Fruit fly) (466 aa), FASTA scores: opt: 790, E(): 6.3e-40, (39.45% identity in 459 aa overlap); etc. Also similar to Q10547|FPRB|Rv0886|MT0909|MTCY31.14 from Mycobacterium tuberculosis strain H37Rv (575 aa), FASTA scores: opt: 894, E(): 4.4e-46, (42.05% identity in 459 aa overlap). Cofactor: FAD |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Predicted secreted protein - identified in culture filtrates of M. tuberculosis H37Rv; signal peptide predicted (See Malen et al., 2007). 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). |
| 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 |
