This article describes the development and creation of the Protein Circular Dichroism Data Bank (PCDDB), a deposition and searchable data bank for validated circular dichroism spectra located at http://pcddb.cryst.bbk.ac.uk/.

Three major classes of lipoproteins (VLDL, d <1.006; LDL, d 1.006-1.040; HDL, d 1.063-1.21) were isolated by ultracentrifugal flotation from the serum of normal male Sprague-Dawley rats. Their physical, chemical, and immunological properties were analyzed and compared with those of their water-soluble, essentially lipid-free derivatives. Studies were also carried out on the d > 1.21 fractions. ...

The validity of three-component fitting of protein circular dichroism (CD) spectra in the peptide absorption region with basis spectra for helical, /?-sheet and unordered structure is examined by matrix rank analysis of protein CD spectra. It is shown that a three-component basis can be justified for several proteins within the limits of experimental error of the spectra. It is suggested that t...

Negative real parts of the permittivity and permeability lead an isotropic chiral medium to exhibit circular dichroism that is reversed with respect to that exhibited by an identical medium but the real parts of whose permittivity and permeability are positive.

We present the first observation of circular dichroism due to a combination of resonant toroidal dipole and electric quadrupole excitations in a toroidal metamaterial.

To unveil the mechanism of fast autooxidation of fish myoglobins, the effect of temperature on the structural change of tuna myoglobin was investigated. Purified myoglobin was subjected to preincubation at 5, 20, 50 and 40C. Overall helical structural decay through thermal treatment up to 95C was monitored by circular dichroism spectrometry, while the structural changes around the heme pocket w...

Gyroid metamaterials are chiral network structures that have the potential to be fabricated through block-copolymer templating. In article number 2200363, Bryan Cote, Vivian Ferry, and co-workers uncover contributions of surface bulk interactions on circular dichroism spectra generated by this metamaterial design. Surface found play a significant role in films silver-infilled gyroid metamateria...
