CC   -!- FUNCTION: Catalyzes the attachment of proline to tRNA(Pro) in a
CC       two-step reaction: proline is first activated by ATP to form Pro-
CC       AMP and then transferred to the acceptor end of tRNA(Pro). As
CC       ProRS can inadvertently accommodate and process non-cognate amino
CC       acids such as alanine and cysteine, to avoid such errors it has
CC       two additional distinct editing activities against alanine. One
CC       activity is designated as 'pretransfer' editing and involves the
CC       tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other
CC       activity is designated 'posttransfer' editing and involves
CC       deacylation of mischarged Ala-tRNA(Pro). The misacylated Cys-
CC       tRNA(Pro) is not edited by ProRS. {ECO:0000255|HAMAP-
CC       Rule:MF_01569}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-proline + tRNA(Pro) = AMP + diphosphate + L-
CC         prolyl-tRNA(Pro); Xref=Rhea:RHEA:14305, Rhea:RHEA-COMP:9700,

CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01569}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01569}.
CC   -!- DOMAIN: Consists of three domains: the N-terminal catalytic
CC       domain, the editing domain and the C-terminal anticodon-binding
CC       domain. {ECO:0000255|HAMAP-Rule:MF_01569}.
CC   -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase
CC       family. ProS type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_01569}.
