Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Catalyzes the attachment of L-tyrosine to tRNA(Tyr) in a two-step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr) (PubMed:4292198, PubMed:4579631). Can also mischarge tRNA(Tyr) with D-tyrosine, leading to the formation of D-tyrosyl-tRNA(Tyr), which can be hydrolyzed by the D-aminoacyl-tRNA deacylase (PubMed:4292198). In vitro, can also use the non-natural amino acid azatyrosine (PubMed:11006270).3 Publications

Magnesium is essential for activity (PubMed:4579631). Inhibited by chloride and sulfate in the presence of 1 mM free Mg2+. When the Mg2+ concentration increases to 10 mM there is almost no chloride inhibition any more. Inhibited by diphosphate and AMP. Chloride strengthens the diphosphate inhibition and weakens the AMP inhibition. Chloride weakens the binding of Mg2+ to the RNA and thereby the interaction between the enzyme and the RNA (PubMed:10572925). Acetylation at certain lysine residues could significantly impair activity (PubMed:28741290). D-tyrosine is a competitive inhibitor of L-tyrosine for the formation of tyrosyl-tRNA(Tyr) (PubMed:4292198).4 Publications

<p>This subsection of the 'Entry information' section provides a mnemonic identifier for a UniProtKB entry, but it is not a stable identifier.

<p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P0AGJ9
Secondary accession number(s): P00951
<p>This subsection of the 'Entry information' section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification ('Last modified'). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical%5Fand%5Fisoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: July 21, 1986

This is version 128 of the entry and version 2 of the sequence. See complete history.
<p>This subsection of the 'Entry information' section indicates whether the entry has been manually annotated and reviewed by UniProtKB curators or not, in other words, if the entry belongs to the Swiss-Prot section of UniProtKB (<strong>reviewed</strong>) or to the computer-annotated TrEMBL section (<strong>unreviewed</strong>).<p><a href='/help/entry_status' target='_top'>More...</a></p>Entry statusiReviewed (UniProtKB/Swiss-Prot)
