PDBsumstructure summary

In molecular biology, 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.[1] Phenylalanine-tRNA synthetase may influence common cellular processes via DNA binding, in addition to its aminoacylation function.
