Figure 4. Interaction of heptapeptide, DNSDNMF with SERA5 catalytic domain.

Figure 4

Panel A shows the interaction of DNSDNMF with SERA5 C by CD spectroscopy. The peptide induced significant conformational change when added with protein in 1∶1 molar ratio. Panel B shows the interaction of DNSDNMF with SERA5 C by spectrofluorimetry. The peptide induced quenching of the tryptophan fluorescence upon incubation with protein in 1∶1 molar ratio.
