CC -!- FUNCTION: Folding helper with both chaperone and peptidyl-prolyl cis-
CC trans isomerase (PPIase) activities. Chaperone activity prevents
CC aggregation of unfolded or partially folded proteins and promotes their
CC correct folding. PPIases catalyze the cis-trans isomerization of Xaa-
CC Pro bonds of peptides, which accelerates slow steps of protein folding
CC and thus shortens the lifetime of intermediates. Both strategies lower
CC the concentration of intermediates and increase the productivity and
CC yield of the folding reaction. SlyD could be involved in Tat-dependent
CC translocation, by binding to the Tat-type signal of folded proteins (By
CC similarity). {ECO:0000250}.
CC -!- FUNCTION: Also involved in hydrogenase metallocenter assembly, probably
CC by participating in the nickel insertion step. This function in
CC hydrogenase biosynthesis requires chaperone activity and the presence
CC of the metal-binding domain, but not PPIase activity (By similarity).
CC {ECO:0000250}.
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;
CC -!- SUBUNIT: Monomer. Binds to a broad range of unrelated Tat signal
CC sequences. Interacts with the hydrogenase nickel incorporation protein
CC HypB (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- DOMAIN: The N-terminal region consists of two globular folded domains
CC that contain prolyl isomerase and chaperone activities. {ECO:0000250}.
CC -!- DOMAIN: The C-terminal region binds nickel ions. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the FKBP-type PPIase family. {ECO:0000305}.
