General Information

Term

mitochondrial tRNA wobble position uridine thiolation

ID (Ontology)

Definition

The process in which a uridine residue at position 34 in the anticodon of a mitochondrial 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:15509579 ]
