Electrostatics of hemoglobins from measurements of the electric dichroism and computer simulations.
TLDR
The calculations demonstrate that the dichroism decay time constants are not simply determined by the size/shape of the proteins, but are strongly influenced by the orientation of the dipole vector with respect to the axis of maximal absorbance.About:

Calculation of hydrodynamic properties of globular proteins from their atomic-level structure.
TL;DR: The solution properties, including hydrodynamic quantities and the radius of gyration, of globular proteins are calculated from their detailed, atomic-level structure, using bead-modeling methodologies described in the previous article, using a HYDROPRO public-domain computer program.

Prediction of Hydrodynamic and Other Solution Properties of Rigid Proteins from Atomic- and Residue-Level Models
TL;DR: The ability to predict hydrodynamic coefficients and other solution properties of rigid macromolecular structures from atomic-level structures, implemented in the computer program HYDROPRO, is extended to models with lower, residue-level resolution, allowing calculations when atomic resolution is not available or coarse-grained models are preferred.
Journal ArticleDOI
A server and database for dipole moments of proteins
TL;DR: There is no obvious relation between a protein's charge or dipole moment and its structure or function, so that its electrostatic properties are highly specific to the particular protein, except that the majority of chains with very large positive charges or dipoles bind to ribosomes or interact with nucleic acids.

Metastable Mesoscopic Clusters in Solutions of Sickle-Cell Hemoglobin
TL;DR: It is shown that solutions of all three Hb variants contain clusters of dense liquid, several hundred nanometers in size, which are metastable with respect to the Hb solutions, and if the clusters are a part of the nucleation mechanism of HbS polymers, the rate of HBS polymerization can be controlled by varying the cluster properties.

TL;DR: These experiments demonstrate that photoactive megadalton protein complexes are compatible with solution processing of organic-semiconductor materials and operate in a dry non-natural environment that is very different from the biological membrane.
