CC -!- FUNCTION: Chaperone involved in the correct folding and assembly of
CC outer membrane proteins. Recognizes specific patterns of aromatic
CC residues and the orientation of their side chains, which are found more
CC frequently in integral outer membrane proteins. May act in both early
CC periplasmic and late outer membrane-associated steps of protein
CC maturation. {ECO:0000256|HAMAP-Rule:MF_01183}.
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:0000256|HAMAP-
CC Rule:MF_01183};
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000256|HAMAP-Rule:MF_01183}.
CC Note=Is capable of associating with the outer membrane.
CC {ECO:0000256|HAMAP-Rule:MF_01183}.
CC -!- DOMAIN: The PPIase activity resides only in the second parvulin domain.
CC The N-terminal region and the C-terminal tail are necessary and
CC sufficient for the chaperone activity of SurA. The PPIase activity is
CC dispensable for SurA to function as a chaperone. The N-terminal region
CC and the C-terminal tail are also required for porin recognition.
CC {ECO:0000256|HAMAP-Rule:MF_01183}.
