11781084-4	2002	In this model, nucleotide binding to the specificity site (s-site) drives formation of an active R1(2)R2(2) dimer, ATP or dATP binding to the adenine-specific site (a-site) results in formation of an inactive tetramer, and ATP binding to the newly described hexamerization site (h-site) drives formation of active R1(6)R2(6) hexamer.	Adenine	142-149	ribonucleotide reductase M2	Mus musculus	102-104
