Hydrophobic interactions: an overview
We present an overview of the recent progress that has been made in understanding the origin of hydrophobic interactions. We discuss the different character of the solvation behaviour of apolar solutes at small and large length scales. We emphasize that the crossover in the solvation behaviour arises from a collective effect, which means that implicit solvent models should be used with care. We...
متن کاملUrea's action on hydrophobic interactions.
For more than a century, urea has been commonly used as an agent for denaturing proteins. However, the mechanism behind its denaturing power is still not well understood. Here we show by molecular dynamics simulations that a 7 M aqueous urea solution unfolds a chain of purely hydrophobic groups which otherwise adopts a compact structure in pure water. The unfolding process arises due to a weake...
متن کاملImportance of Hydrophobic Motif Interactions
INTRODUCTION The Serum and Glucocorticoid regulated kinases (SGK) are a family of serine/threonine protein kinases that show extensive sequence homology to the Protein Kinase B (PKB/Akt) enzymes. Three isoforms exist in humans: SGK1, SGK2 and SGK3. Like PKB, SGK1 acts downstream of phosphatidylinositol-3-kinase (PI3K) (1). PKB requires phosphorylation of its activation loop and of a hydrophobic...
متن کاملHydrophobic interactions in metalloporphyrin-peptide complexes.
The study of synthetic analogues of heme proteins has been thorough and successful.1 Despite many accomplishments, however, there remains a fundamental difference between the heme proteins themselves and the small molecules that mimic them; the analogues are generally not made from peptides, and the interactions between the heme and the protein remain largely unexplored.2 The few exceptions are...
متن کاملRecent progress in understanding hydrophobic interactions.
We present here a brief review of direct force measurements between hydrophobic surfaces in aqueous solutions. For almost 70 years, researchers have attempted to understand the hydrophobic effect (the low solubility of hydrophobic solutes in water) and the hydrophobic interaction or force (the unusually strong attraction of hydrophobic surfaces and groups in water). After many years of research...
