Escherichia coli K-12 substr. MG1655 Gene-Ontology-Terms Class: GO:0006400 - tRNA modification

Synonyms: GO:0016549

Definition: 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.

Summary:
The term 'RNA editing' (GO:0016547) was merged into 'RNA modification' (GO:0009451) on the basis of statements in the preface of Modification and Editing of RNA (ISBN:1555811337) that there is no clear distinction between modification and editing. Parallel changes were made for substrate (e.g. tRNA, rRNA, etc.) specific child terms of 'RNA editing'.
