RT   "Complete sequence of Chloroherpeton thalassium ATCC 35110.";
RL   Submitted (JUN-2008) to the EMBL/GenBank/DDBJ databases.
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:0000255|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         EC=6.1.1.15; Evidence={ECO:0000255|HAMAP-Rule:MF_01571};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01571}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|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:0000255|HAMAP-Rule:MF_01571}.
CC   -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC       ProS type 3 subfamily. {ECO:0000255|HAMAP-Rule:MF_01571}.
