CC   -!- FUNCTION: Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two-
CC       step reaction: tyrosine is first activated by ATP to form Tyr-AMP and
CC       then transferred to the acceptor end of tRNA(Tyr). {ECO:0000255|HAMAP-
CC       Rule:MF_02007}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-tyrosine + tRNA(Tyr) = AMP + diphosphate + H(+) + L-
CC         tyrosyl-tRNA(Tyr); Xref=Rhea:RHEA:10220, Rhea:RHEA-COMP:9706,

CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_02007}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02007}.
CC   -!- SIMILARITY: Belongs to the class-I aminoacyl-tRNA synthetase family.
CC       TyrS type 2 subfamily. {ECO:0000255|HAMAP-Rule:MF_02007}.
