Gene Rv3048c (nrdG)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in the DNA replication pathway. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides, precursors that are necessary for DNA synthesis [catalytic activity: 2'-deoxyribonucleoside diphosphate + oxidized thioredoxin + H(2)O = ribonucleoside diphosphate + reduced thioredoxin]. |
| Product | Ribonucleoside-diphosphate reductase (beta chain) NrdF2 (ribonucleotide reductase small subunit) (R2F protein) |
| Comments | Rv3048c, (MTV012.63c), len: 324 aa. NrdF2, ribonucleoside-diphosphate reductase, beta chain (see citation below), equivalent to Q9CBQ2|RIR2_MYCL|NRDF|ML1731 ribonucleoside-diphosphate reductase beta chain from Mycobacterium leprae (325 aa), FASTA scores: opt: 2009, E(): 1.3e-123, (93.5% identity in 324 aa overlap). Also similar to other ribonucleoside-diphosphate reductases e.g. Q9XD62|NRDF from Corynebacterium glutamicum (Brevibacterium flavum) (334 aa), FASTA scores: opt: 1648, E(): 4.2e-100, (78.35% identity in 314 aa overlap); O69274|NRDF from Corynebacterium ammoniagenes (Brevibacterium ammoniagenes) (329 aa), FASTA scores: opt: 1626, E(): 1.1e-98, (75.3% identity in 320 aa overlap); P37146|NRDF|B2676 from Escherichia coli (319 aa), FASTA scores: opt: 1569, E(): 5.7e-95, (71.3% identity in 317 aa overlap). Contains PS00368 Ribonucleotide reductase small subunit signature. Belongs to the ribonucleoside diphosphate reductase small chain family. Cofactor: binds 2 iron ions (by similarity). Note that previously known as nrdG. |
| Functional category | Information pathways |
| 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 culture filtrate and membrane protein fraction of M. tuberculosis H37Rv but not whole cell lysates (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). M. tuberculosis H37Rv nrdR|Rv2718c mutant has increased expression of nrdE|Rv3051c and nrdF2|Rv3048c (See Mowa et al., 2009). Check for mutants available at TARGET website |
