General Information

Term

tRNA wobble position uridine thiolation

ID (Ontology)

GO:0002143 (Gene Ontology)

Definition

The process in which a uridine residue at position 34 in the anticodon of a tRNA is post-transcriptionally thiolated at the C2 position. This process involves transfer of a sulfur from L-cysteine to position C2 by several steps.[ PubMed:16871210 ]

Also Known As
