products description :
Background: SlyD is a putative folding helper protein from the Escherichia coli cytosol, which consists of an N-terminal prolyl isomerase domain of the FKBP type and a presumably unstructured C-terminal tail. It is involved in the biosynthesis of the metal cluster in the [NiFe]-hydrogenase enzymes, and exhibits several activities including that of a peptidyl-prolyl isomerase.

ncbi summary :
HypB requires binding of SlyD for hydrogenase activity as SlyD helps facilitate nickel insertion. [More information is available at EcoGene: EG11663]. SlyD is a peptidyl prolyl cis/trans-isomerase (PPIase) and chaperone. [More information is available at EcoCyc: EG11663].
uniprot summary :
Folding helper with both chaperone and peptidyl-prolyl cis-trans isomerase (PPIase) activities. Chaperone activity prevents aggregation of unfolded or partially folded proteins and promotes their correct folding. PPIases catalyze the cis-trans isomerization of Xaa-Pro bonds of peptides, which accelerates slow steps of protein folding and thus shortens the lifetime of intermediates. Both strategies lower the concentration of intermediates and increase the productivity and yield of the folding reaction. SlyD could be involved in Tat-dependent translocation, by binding to the Tat-type signal of folded proteins. The PPIase substrate specificity, carried out with synthetic peptides of the 'suc-Ala-Xaa-Pro-Phe-4NA' type (where Xaa is the AA tested), was found to be Phe > Ala > Leu.
