  • GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • GO:0046872 Binding to a metal ion.
  • GO:0008479 Catalysis of the reaction: guanosine34 in tRNA + queuine = guanine + queuosine34 in 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.
  • GO:0002099 The process in which a guanine at position 34 of a tRNA is post-transcriptionally modified. The wobble nucleoside of the tRNA sequence (position 34) corresponds to the first position of the anticodon.
  • GO:0016763 Catalysis of the transfer of a pentosyl group from one compound (donor) to another (acceptor).
  • GO:0006400 The covalent alteration of one or more nucleotides within a tRNA molecule to produce a tRNA molecule with a sequence that differs from that coded genetically.
  • GO:0101030 OBSOLETE. The modification of a tRNA anticodon loop by replacing guanine with queuonine. Reaction is tRNA guanine + queuine = tRNA queuine + guanine.
