The SlyD metallochaperone targets iron-sulfur biogenesis pathways and the TCA cycle.

ABSTRACT:

Importance

Correct folding of proteins represents a crucial step for their functions. Among the chaperones that control protein folding, the ubiquitous PPIases catalyze the cis/trans-isomerization of peptidyl-prolyl bonds. Only few protein targets of PPIases have been reported in bacteria. To fill this knowledge gap, we performed a large-scale two-hybrid screen to search for targets of the Escherichia coli and Helicobacter pylori SlyD PPIase-metallochaperone. SlyD from both organisms interacts with enzymes (i) containing metal cofactors, (ii) from the central metabolism tricarboxylic acid (TCA) cycle, and (iii) involved in the formation of the essential and ancestral Fe-S cluster cofactor. E. coli and H. pylori ∆slyD mutants present similar
