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). Can inadvertently
CC accommodate and process cysteine. Misacylated Cys-tRNA(Pro) is not
CC edited by ProRS; this function may be provided by ProX.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-proline + tRNA(Pro) = AMP + diphosphate + L-prolyl-

CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.05 mM for proline {ECO:0000269|PubMed:12130657};
CC KM=0.01 mM for cysteine {ECO:0000269|PubMed:12130657};
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm.
CC -!- DOMAIN: Consists of three domains: the N-terminal catalytic domain, the
CC anticodon-binding domain and the C-terminal extension. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC ProS type 3 subfamily. {ECO:0000305}.
