Protein Domain
Type: Family
Description: The beta (small) subunit of ribonucleotide reductase (RNR) is a member of a broad superfamily of ferritin-like diiron-carboxylate proteins. The RNR protein catalyzes the conversion of ribonucleotides to deoxyribonucleotides and is found in all eukaryotes, many prokaryotes, several viruses, and few archaea. The catalytically active form of RNR is a proposed alpha2-beta2 tetramer. The homodimeric alpha subunit (R1) contains the active site and redox active cysteines as well as the allosteric binding sites. The beta subunit (R2) contains a di-iron cluster that, in its reduced state, reacts with dioxygen to form a stable tyrosyl radical and a di-iron(III) cluster. This essential tyrosyl radical is proposed to generate a thiyl radical, located on a cysteine residue in the R1 active site that initiates ribonucleotide reduction. The beta subunit is composed of 10-13 helices, the eight longest helices form an α-helical bundle; some have two addition beta strands [, , , ].The beta-herpesvirus RNR R1 subunit homologues are catalytically inactive; the enzyme seem to function by inhibiting cellular adaptor protein RIP1 to block cellular signaling pathways involved in innate immunity and inflammation [].Yeast is unique in that it assembles both homodimers and heterodimers of RNR. The yeast heterodimer, Y2Y4, contains R2 (Y2) and a R2 homologue (Y4) that lacks the diiron centre and is proposed to only assist in cofactor assembly, and perhaps stabilize R1 (Y1) in its active conformation [, ]. In mammals, the active form of the enzyme is composed of two identical large subunits (RRM1) and two identical small subunits (RRM2 or its homologue RRM2B). RRM1 is the catalytic subunit, and RRM2 and RRM2B the regulatory subunits. RRM2B (also called p53R2) can be induced by p53 [, ].

The homodimeric alpha subunit (R1) contains the active site and redox active cysteines as well as the allosteric binding sites. The beta subunit (R2) contains a di-iron cluster that, in its reduced state, reacts with dioxygen to form a stable tyrosyl radical and a di-iron(III) cluster. This essential tyrosyl radical is proposed to generate a thiyl radical, located on a cysteine residue in the R1 active site that initiates ribonucleotide reduction. The beta subunit is composed of 10-13 helices, the eight longest helices form an α-helical bundle; some have two addition beta strands [, , , ].The beta-herpesvirus RNR R1 subunit homologues are catalytically inactive; the enzyme seem to function by inhibiting cellular adaptor protein RIP1 to block cellular signaling pathways involved in innate immunity and inflammation [].Yeast is unique in that it assembles both homodimers and heterodimers of RNR. The yeast heterodimer, Y2Y4, contains R2 (Y2) and a R2 homologue (Y4) that lacks the diiron centre and is proposed to only assist in cofactor assembly, and perhaps stabilize R1 (Y1) in its active conformation [, ]. In mammals, the active form of the enzyme is composed of two identical large subunits (RRM1) and two identical small subunits (RRM2 or its homologue RRM2B). RRM1 is the catalytic subunit, and RRM2 and RRM2B the regulatory subunits. RRM2B (also called p53R2) can be induced by p53 [, ].This entry includes the ribonucleoside-diphosphate reductase small subunit from Herpesviruses.
