Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

Miscellaneous

The glycyl radical is involved in generation of a transient thiyl (sulfanyl) radical on a cysteine residue, which attacks the substrate, forming a ribonucleotide 3'-radical, followed by water loss to form a ketyl (alpha-oxoalkyl) radical. The ketyl radical gains an electron from a cysteine residue and a proton from formic acid, forming 3'-keto-deoxyribonucleotide and generating a thiosulfuranyl radical bridge between methionine and cysteine residues. Oxidation of formate by the thiosulfuranyl radical results in the release of CO2 and regeneration of the thiyl radical.1 Publication

Activated under anaerobic conditions by NrdG, a tightly associated activase (PubMed:1460049, PubMed:7852304, PubMed:9305874). Activation involves the formation of a glycyl radical at Gly-681 (PubMed:7852304, PubMed:8636106, PubMed:9305874). Exposure of the activated reductase to oxygen leads to C-terminal truncation and inactivation of the protein, by cleavage at the N-terminal side of Gly-681 (PubMed:8421692, PubMed:7826394). The presence of zinc protects the protein from proteolysis and prevents the formation of disulfide bridges within it (PubMed:19381696).7 Publications
