Enantiomerically pure beta-amino acid derivs. with the side-chains of Ala, Val, and Leu in the 2- or 3-position (β2- and β3-amino acids, resp.), as well as with substituents in both the 2- and 3-positions (β2,3-amino acids, of like-configuration) were prep ...
To test the effect of NH-C(=S) groups on the stability of beta-peptide secondary structures, the authors have synthesized three beta-thiohexapeptide analogs I (X = S, Y = Z = O; X = Z = S, Y = O; X = Y = Z = S) of H-(beta-HVal-beta-HAla-beta-HLeu)2-OH I (X ...
A simple approach to the in situ measurement of IR spectra of self-assembled monolayers (SAMs) on gold in an aq. environment is described. A thin gold film (3-5 nm) on the surface of a germanium internal reflection element is used as a substrate for the se ...
A series of novel, surface-active, inorganometallic complexes of osmium were synthesized and then characterized (using electrochemical techniques) as electron transfer mediators for glucose oxidase (EC 1.1.3.4, GOD) from Aspergillus niger. The mediators co ...
State-selected spectra of the OH stretch overtones of methanol in the range of upsilon(1) = 3-8 reveal spectral splittings and broadenings that result from vibrational couplings within the molecule. We employ a two-color excitation technique in which an in ...
With 71 refs., this review presents various aspects of beta-peptides (oligomers of beta-amino acids): synthesis, structure detn. by NMR and CD, thermal stability properties, helical and beta-pleated secondary structures, peptide folding, biol. and pharmaco ...
A serotonin 5-HT3 receptor was functionally expressed to high levels and on a large scale in mammalian cells with the Semliki Forest virus system. Conditions were optimized to maximize detergent solubilization of the receptor, while preserving ligand bindi ...
We demonstrate the implementation of a thin film pyroelectric array as a detector in an infrared gas spectrometer. The 1 x 50 element array is integrated onto a silicon chip with a sol-gel deposited zirconium modified lead titanate film (PZT) as the pyroel ...
Proteolytic activation, oligomerization, and membrane insertion are three steps that precede channel formation by the bacterial toxin aerolysin. Using attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and hydrogen-deuterium exc ...
beta-Hexapeptides and a beta-dodecapeptide with sequences contg. two different types of beta-amino acids, aliph. proteinaceous side-chains in 2- or 3-position, were studied with CD and NMR measurements. With one exception, the secondary structures formed b ...
