CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-phenylalanine + tRNA(Phe) = AMP + diphosphate + H(+) +
CC L-phenylalanyl-tRNA(Phe); Xref=Rhea:RHEA:19413, Rhea:RHEA-COMP:9668,
CC Rhea:RHEA-COMP:9699, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:58095, ChEBI:CHEBI:78442,
CC ChEBI:CHEBI:78531, ChEBI:CHEBI:456215; EC=6.1.1.20;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00283};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00283};
CC Note=Binds 2 magnesium ions per tetramer. {ECO:0000255|HAMAP-
CC Rule:MF_00283};
CC -!- SUBUNIT: Tetramer of two alpha and two beta subunits.
CC {ECO:0000255|HAMAP-Rule:MF_00283}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00283}.
CC -!- SIMILARITY: Belongs to the phenylalanyl-tRNA synthetase beta subunit
CC family. Type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_00283}.
CC -!- CAUTION: Lacks 2 conserved residues that bind magnesium; the aspartate
CC residue in position 464 is replaced by an asparagine and the glutamate
CC residue in position 467 is replaced by a serine residue. {ECO:0000305}.
