Comments [?]

FUNCTION	Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro).
CATALYTIC ACTIVITY	Reaction=ATP + L-proline + tRNA(Pro) = AMP + diphosphate + L-prolyl- tRNA(Pro); Xref=Rhea:RHEA:14305, Rhea:RHEA-COMP:9700, Rhea:RHEA- COMP:9702, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:60039, ChEBI:CHEBI:78442, ChEBI:CHEBI:78532, ChEBI:CHEBI:456215; EC=6.1.1.15;
SUBUNIT	Homodimer.
SUBCELLULAR LOCATION	Cytoplasm.
DOMAIN	Consists of three domains: the N-terminal catalytic domain, the anticodon-binding domain and the C-terminal extension.
SIMILARITY	Belongs to the class-II aminoacyl-tRNA synthetase family. ProS type 3 subfamily.
