Ribonucleotide reductase-like (IPR012348)

Short name: RNR-like

Overlapping entries


The R2 protein of ribonucleotide reductase catalyses the reduction of all four ribonucleotides to deoxyribonucleotides for use in DNA synthesis. This catalysis involves generating and storing a tyrosyl radical, which is essential for ribonucleotide reduction. The crystal structure consists of a core of four helices in a closed bundle with a left-handed twist and one crossover connection, and a bimetal-ion centre in the middle of the bundle [PMID: 8876648].

This entry represents proteins that are structurally related to the R2 protein of class I ribonucleotide reductase, including the alpha and beta subunits of methane monooxygenase, and delta 9-stearoyl-acyl carrier protein desaturase [PMID: 8749363].
