CD can provide several crucial pieces of information about catalysts:
Secondary structure: CD spectra can indicate the presence of α-helices, β-sheets, and random coils in protein catalysts. Conformational changes: CD can monitor changes in the conformation of catalysts upon substrate binding or during catalysis. Chirality: CD is sensitive to the chiral environment of catalysts, helping to elucidate the stereochemistry at the active site. Binding interactions: CD can detect changes in the optical activity of catalysts upon interaction with substrates or inhibitors.
