Interfacial Rheology of Globular Proteins
Protein-surfactant mixtures appear in many industrial and biological applications. Indeed, a fluid as vital as blood contains a mixture of serum albumin proteins with various other smaller surface-active components. Proteins and other surface active molecules are often adsorbed at an air-liquid or liquid-liquid interface due to favorable thermodynamics, and these interfaces play a role in such ...
متن کاملAeolotopic interactions of globular proteins.
Protein crystallization, aggregation, liquid-liquid phase separation, and self-assembly are important in protein structure determination in the industrial processing of proteins and in the inhibition of protein condensation diseases. To fully describe such phase transformations in globular protein solutions, it is necessary to account for the strong spatial variation of the interactions on the ...
متن کاملFolding units in globular proteins.
We present a method to identify all compact, contiguous-chain, structural units in a globular protein from x-ray coordinates. These units are then used to describe a complete set of hierarchic folding pathways for the molecule. Our analysis shows that the larger units are combinations of smaller units, giving rise to a structural hierarchy ranging from the whole protein monomer through supersec...
متن کاملLoop fold nature of globular proteins.
Protein chains make numerous returns in globules, thus forming loops, closed by tight residue-to-residue contacts-closed loops. Previous statistical analysis of the sizes and locations of the closed loops in all major protein folds revealed that the loops have an almost standard contour length of 25-30 amino acid residues and follow one after another along the chain. In this work the closed loo...
متن کاملIv. Protein Interactions Aggregation of Globular Proteins
Many globular proteins are known to polymerize. It is pointed out that a monomer protein molecule containing a single polypeptide chain is asymmetric, and that a single pair of complementary combining regions on such a molecule would permit it to attach itself to equivalent molecules in such a way as to form a helical structure, giving rise to fibrils. If the pitch of the helix is zero or nearl...
