CC -!- FUNCTION: Catalyzes the attachment of proline to tRNA(Pro) in a two-
CC step reaction: proline is first activated by ATP to form Pro-AMP and
CC then transferred to the acceptor end of tRNA(Pro). {ECO:0000256|HAMAP-
CC Rule:MF_01571}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-proline + tRNA(Pro) = AMP + diphosphate + L-prolyl-
CC tRNA(Pro); Xref=Rhea:RHEA:14305, Rhea:RHEA-COMP:9700, Rhea:RHEA-
CC COMP:9702, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:60039,
CC ChEBI:CHEBI:78442, ChEBI:CHEBI:78532, ChEBI:CHEBI:456215;
CC EC=6.1.1.15; Evidence={ECO:0000256|HAMAP-Rule:MF_01571};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01571}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01571}.
CC -!- DOMAIN: Consists of three domains: the N-terminal catalytic domain, the
CC anticodon-binding domain and the C-terminal extension.
CC {ECO:0000256|HAMAP-Rule:MF_01571}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC ProS type 3 subfamily. {ECO:0000256|HAMAP-Rule:MF_01571}.
