    Interactioni

    Subunit structurei

    Heterotetramer of two large (R1) and two small (R2) subunits. S.cerevisiae has two different R1 subunits (RNR1 and RNR3) and two different R2 subunits (RNR2 and RNR4). The functional form of the small subunits is a RNR2-RNR4 heterodimer, where RNR2 provides the iron-radical center and RNR4 is required for proper folding of RNR2 and assembly with the large subunits. Under normal growth conditions, the active form of the large subunits is a homodimer of the constitutively expressed RNR1. In damaged cells or cells arrested for DNA synthesis, the reductase consists of multiple species because of the association of the small subunits (RNR2-RNR4) with either the RNR1 homodimer or a heterodimer of RNR1 and the damage-inducible RNR3. Interacts with DIF1.3 Publications
