Characterization of fold diversity among proteins with the same number of amino acid residues

Tidskriftsartikel (refereegranskat)abstract
- Chain entanglements provide a simple and global measure of folding in a macromolecule. The complexity of these entanglements can be expressed by the pattern of projected bond-bond crossings, or "overcrossings", associated with the molecular backbone. In t

Compaction of grafted wormlike chains under variable confinement

Tidskriftsartikel (refereegranskat)abstract
- We study the mean molecular shape features for a model of wormlike chains with variable persistence length and nonbonded pair interactions. The chains are modelled as end-grafted and confined within an infinite slab with variable thickness. By using two i

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- A quantitative characterization of entanglements between polymer chains is essential for understanding the behavior of polymer solutions. When dealing with unknotted open chains, that characterization must rely on geometrical (rather than topological) mea

Quantitative measure of folding in two-dimensional polymers

Ingår i: PHYSICAL REVIEW E. - : AMERICAN PHYSICAL SOC. - 1063-651X. ; 59:4, s. 4209-4215
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The degree of folding of a single three-dimensional (3D) polymer configuration is a general concept associated with the pattern of interpenetrations between chain loops. In the present context, this notion applies to the state of a rigid chain, regardless

Shape transitions in confined polymer mushrooms with excluded-volume interaction

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This work deals with some aspects of the molecular shape deformation of a single grafted poly mer (a "polymer mushroom") compressed by a repulsive wall. Compression not only changes the size of the polymer but also modifies its entanglements, i.e., how th

Structural transitions in neutral and charged proteins in vacuo

-
Tidskriftsartikel (refereegranskat)abstract
- In vacuo proteins provide a simple laboratory to explore the roles of sequence, temperature, charge state, and initial configuration in protein folding. Moreover, by the very absence of solvent, the study of anhydrous proteins in vacuo will also help us t
