Circular dichroism beta sheet
WebThis paper reviews the best known techniques using circular dichroism spectroscopy such as conventional circular dichroism ... 75% for beta sheet, 50% for turns, and 89% for other secondary structures, respectively . Scans in the ‘near-UV’ range, i.e. 250–300 nm, give information about tertiary structure. WebThe circular dichroism spectra recorded in far UV region (far UV-CD) can solve the secondary structure of proteins. Based on the CD spectra, α-helical proteins possess negative bands at 222 nm and 208 nm and a positive one at 193 nm. Proteins with β-sheet conformation have negative bands at 218 nm and positive bands at 195 nm.
