RT "Complete sequence of Thermotoga sp. RQ2.";
RL Submitted (MAR-2008) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Involved in protein export. Acts as a chaperone by
CC maintaining the newly synthesized protein in an open conformation.
CC Functions as a peptidyl-prolyl cis-trans isomerase. {ECO:0000255|HAMAP-
CC Rule:MF_00303}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[protein]-peptidylproline (omega=180) = [protein]-
CC peptidylproline (omega=0); Xref=Rhea:RHEA:16237, Rhea:RHEA-
CC COMP:10747, Rhea:RHEA-COMP:10748, ChEBI:CHEBI:83833,
CC ChEBI:CHEBI:83834; EC=5.2.1.8; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00303};
CC -!- SUBCELLULAR LOCATION: Cytoplasm. Note=About half TF is bound to the
CC ribosome near the polypeptide exit tunnel while the other half is free
CC in the cytoplasm. {ECO:0000255|HAMAP-Rule:MF_00303}.
CC -!- DOMAIN: Consists of 3 domains; the N-terminus binds the ribosome, the
CC middle domain has PPIase activity, while the C-terminus has intrinsic
CC chaperone activity on its own. {ECO:0000255|HAMAP-Rule:MF_00303}.
CC -!- SIMILARITY: Belongs to the FKBP-type PPIase family. Tig subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00303}.
