B5

tRNA synthetase B5 domain
B5
SMART accession number:SM00874
Description: This domain is found in phenylalanine-tRNA synthetase beta subunits.
Interpro abstract (IPR005147):

Domain B5 is found in phenylalanine-tRNA synthetase beta subunits. This domain has been shown to bind DNA through a winged helix-turn-helix motif [(PUBMED:11152603)]. Phenylalanine-tRNA synthetase may influence common cellular processes via DNA binding, in addition to its aminoacylation function.

GO process:phenylalanyl-tRNA aminoacylation (GO:0006432)
GO function:RNA binding (GO:0003723), magnesium ion binding (GO:0000287), ATP binding (GO:0005524)
Family alignment:
