UniProt functional annotation for P17424

UniProt code: P17424.

Organism: Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720).
Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Salmonella.
 
Function: Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R2F contains the tyrosyl radical required for catalysis.
 
Catalytic activity: Reaction=[thioredoxin]-disulfide + a 2'-deoxyribonucleoside 5'- diphosphate + H2O = [thioredoxin]-dithiol + a ribonucleoside 5'- diphosphate; Xref=Rhea:RHEA:23252, Rhea:RHEA-COMP:10698, Rhea:RHEA- COMP:10700, ChEBI:CHEBI:15377, ChEBI:CHEBI:29950, ChEBI:CHEBI:50058, ChEBI:CHEBI:57930, ChEBI:CHEBI:73316; EC=1.17.4.1; Evidence={ECO:0000255|PROSITE-ProRule:PRU10014};
Cofactor: Name=Fe cation; Xref=ChEBI:CHEBI:24875; Note=Binds 2 iron ions per subunit.;
Pathway: Genetic information processing; DNA replication.
Subunit: Tetramer of two alpha and two beta subunits. {ECO:0000250}.
Similarity: Belongs to the ribonucleoside diphosphate reductase small chain family. {ECO:0000305}.
