Functional Annotations
Enzyme classification and Gene Ontology terms linked to this protein.
Enzyme Commission (EC)
1Gene Ontology (GO)
3- GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
- GO:0051075 Catalysis of the reaction: S-adenosylmethionine + 7-(aminomethyl)-7-deazaguanosine-tRNA = adenine + methionine + epoxyqueuosine-tRNA. 7-(aminomethyl)-7-deazaguanosine-tRNA is also known as preQ1-tRNA, and epoxyqueuosine-tRNA as oQ-tRNA.
- GO:0008616 The chemical reactions and pathways resulting in the formation of queuosines, a series of nucleosides found in position 34 of tRNA and having an additional pentenyl ring added via an NH group to the methyl group of 7-methylguanosine. The pentenyl ring may carry other substituents. The wobble nucleoside of the tRNA sequence (position 34) corresponds to the first position of the anticodon.
