FunFam 33: Phenylalanine--tRNA ligase alpha subunit

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 4 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Aminoacyl-tRNA editing activity GO:0002161
The hydrolysis of an incorrectly aminoacylated tRNA.
1 Q9W3J5 (/IMP)
Phenylalanine-tRNA ligase activity GO:0004826
Catalysis of the reaction: ATP + L-phenylalanine + tRNA(Phe) = AMP + diphosphate + L-phenylalanyl-tRNA(Phe).
1 Q9W3J5 (/IDA)
Phenylalanine-tRNA ligase activity GO:0004826
Catalysis of the reaction: ATP + L-phenylalanine + tRNA(Phe) = AMP + diphosphate + L-phenylalanyl-tRNA(Phe).

There are 7 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Negative regulation of transcription by RNA polymerase II GO:0000122
Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.
1 Q86B36 (/IMP)
Translation GO:0006412
The cellular metabolic process in which a protein is formed, using the sequence of a mature mRNA or circRNA molecule to specify the sequence of amino acids in a polypeptide chain. Translation is mediated by the ribosome, and begins with the formation of a ternary complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2, which subsequently associates with the small subunit of the ribosome and an mRNA or circRNA. Translation ends with the release of a polypeptide chain from the ribosome.
1 Q86B36 (/IMP)
Phenylalanyl-tRNA aminoacylation GO:0006432
The process of coupling phenylalanine to phenylalanyl-tRNA, catalyzed by phenylalanyl-tRNA synthetase. The phenylalanyl-tRNA synthetase is a class-II synthetase. However, unlike other class II enzymes, The activated amino acid is transferred to the 2'-OH group of a phenylalanine-accepting tRNA. The 2'-O-aminoacyl-tRNA will ultimately migrate to the 3' position via transesterification.
1 Q9W3J5 (/IDA)
Phenylalanyl-tRNA aminoacylation GO:0006432
