The circular dichroism of tumor necrosis factor-alpha: measurement into the vacuum UV and analysis for secondary structure.
The circular dichroism (CD) spectrum of tumor necrosis factor-alpha has been measured into the vacuum UV to 168 nm. Analysis of the CD for secondary structure is in good agreement with X-ray diffraction results, but the analysis is somewhat unstable. Adding the CD of this protein together with its X-ray determined secondary structure to the basis set should improve subsequent analyses of CD spectra for other all-beta proteins.
