KEOPS tRNA N6-adenosine threonylcarbamoyltransferase complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.

Summary
Catalyses the transfer of the threonylcarbamoyl-moiety of threonylcarbamoyladenylate (TCA) onto A37 of substrate tRNA in the cytoplasm. The N6-threonylcarbamoyladenosine (t6A) modification is present at position 37 of tRNAs that recognize ANN-codons, with N being any nucleotide, enhancing the codon-anti-codon interaction and is required for recognition of the AUG start codon. The modification is thus important for maintaining translational fidelity and also appears to play a role in transcription and telomere homeostasis. The unstable TCA intermediate is synthesised from ATP, threonine and bicarbonate by the SUA5 (P32579) enzyme.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.

acyltransferase activity, ion binding, transferase activity, DNA metabolic process, RNA modification, biosynthetic process, chromosome organization, tRNA metabolic process, tRNA processing, telomere organization

Biological Process

Manually curated GO annotations reflect our best understanding of the basic biological process for this protein complex. Manually curated annotations are assigned by curators based on published papers when available, or by curatorial statements if necessary. Curators periodically review all manually curated GO annotations for accuracy and completeness.

Shared Annotations

This diagram displays Gene Ontology terms (green) that are shared between the given macromolecular complex (black) and other yeast complexes (yellow). Note: No diagram is shown ("No shared annotations") if there are less than 2 shared GO annotations between this complex and any other complexes.
