Effects of pH, ionic strength, calcium, and molecular mass on the arrangement of hydrophobic peptides helices at the air-water interface
Article Abstract:
The influence of subphase characteristics on the conformation and lateral and lateral orientation of the hydrophobic polypeptide poly-L-leucine at the air-water interface with the surface film balance technique as well as with Brewster angle microscopy (BAM) is investigated. Kinetics studies of monolayer relaxation strongly suggest that the end-group effects influence the thermodynamic, as well as the kinetic, properties of peptide monolayers.

Conformational equilibrium in alanine-rich peptides probed by reversible stretching
Article Abstract:
Reversible stretching of the alanine-rich peptide 3K and its analogue MW is investigated by using molecular dynamics simulations in explicit water. The association of adaptive biasing force (ABF) method with a simple collective degree of freedom has proved to constitute a well-adapted and efficient scheme for sampling the transition between helical and extended forms of short peptides in water.

Modeling the electrophoresis of peptides and proteins: Improvements in the "bead Method" to include ion relaxation and "finite size effects"
Article Abstract:
A methodology used to determine unrelaxed mobilities [mu]m of model peptides and proteins including finite bead size effects is outlined and the method used to account icon relaxation is examined. It is learnt that the effects of ion relaxation can be significant if the absolute electrophoretic mobility of a peptide exceeds approximately 0.20 [cm.sup.2]/ (kV s).
