Gene Rv1981c (nrdF)
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) NrdF1 (ribonucleotide reductase small subunit) (R2F protein) | 
| Comments | Rv1981c, (MTCY39.38), len: 322 aa. NrdF1, ribonucleoside-diphosphate reductase, beta chain (see citation below), highly similar to others e.g. RIR4_SALTY|P17424 ribonucleoside-diphosphate reductase (319 aa), FASTA scores: opt: 1402, E(): 0, (66.0% identity in 315 aa overlap); etc. Also similar to Rv3048c|MTV012.63c from Mycobacterium tuberculosis. 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 nrdF. | 
| Functional category | Information pathways | 
| Proteomics | Identified by mass spectrometry in the culture filtrate of M. tuberculosis H37Rv but not the membrane protein fraction or whole cell lysates (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). Disruption of this gene provides a growth advantage for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Growth of M. tuberculosis H37Rv nrdF1|Rv1981c mutant is comparable to wild-type in vitro, in vitro in the presence of various drugs and stresses, and in vivo in B6D2/F1 mouse lungs (See Mowa et al., 2009).
