The relative importance of electrostatic and nonelectrostatic interactions in peptide-microgel systems was evaluated by micromanipulator-assisted light microscopy, confocal microscopy, and circular dichroism. For this purpose, the interaction of various homopolypeptides with lightly cross-linked polyelectrolyte gel particles ( approximately 70 microm

Bent but not broken: cyclic oligoprolines are accessed in a reaction that effectively bends rigid oligoproline peptides (see scheme; TBDMS=tert-butyldimethylsilyl). The stitching is accomplished during macrocyclization enabled by aziridine aldehydes and isocyanides. Molecular modeling studies suggest that electrostatic attraction between

Proline is incompatible with ideal β-sheet geometry, and the incompatibility gets magnified when Pro assumes the cis peptidyl-prolyl conformation. We show that Gly appears with high propensity at pre-cisPro positions in β-sheets and rescues the β-sheet from severe distortions by

Modified HABP (mHABP) regions interacting with HLA-DRβ1(∗) molecules have a more restricted conformation and/or sequence than other mHABPs which do not fit perfectly into their peptide binding regions (PBR) and do not induce an acceptable immune response due to the

The poly-l-proline type II (PPII) helix in recent years has emerged clearly as a structural class not only of fibrillar proteins (in collagen, PPII is a dominant conformation) but also of the folded and unfolded proteins. Although much less abundant


Poly(Amino Acid) Block Copolymers for Drug Delivery and other Biomedical Applications

Humankind has utilized protein materials throughout its existence, starting with the use of materials such as wool and silk for warmth and protection from the elements and continuing with the use of recombinant DNA techniques to synthesize proteins with unique and useful properties.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
