Chemical shift mapping of PrsA-PPIase during Suc-AXPF- p NA titrations. Chemical shift perturbations induced to the backbone amide signals of S. aureus PrsA-PPIase upon Suc-AXPF-p NA (X = A, K or E) peptide titration. Position of the secondary structure elements in the sequence is shown at the top of the graph: green arrow – β-strand, red bar – α-helix. Structure insert shows the location of residues which evinced the largest chemical shift perturbations in the Suc-AEPF-p NA titration (red – Δδ > 0.03 ppm).
