FunFam 266627: Phenylalanine--tRNA ligase alpha subunit

There are 2 EC terms in this cluster

Please note: EC 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.

Note: 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.

EC Term Annotations Evidence
Phenylalanine--tRNA ligase. [EC: 6.1.1.20]
ATP + L-phenylalanine + tRNA(Phe) = AMP + diphosphate + L-phenylalanyl- tRNA(Phe).

    Repressor LexA. [EC: 3.4.21.88]
    Hydrolysis of Ala-|-Gly bond in repressor LexA.
    • In the presence of single-stranded DNA, the RecA protein interacts with LexA causing an autocatalytic cleavage which disrupts the DNA- binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
    • The activity was previously attributed to the RecA protein (formerly EC 3.4.99.37).
    • Belongs to peptidase family S24.
