Side chain‐to‐side chain cyclization by click reaction

Journal of Peptide Science, 2009
AbstractCuI‐catalyzed azide‐alkyne 1,3‐dipolar Huisgen's cycloaddition (CuAAC) is a click reaction that has drawn a lot of attention, in general, and in the field of peptide and protein sciences, in particular. Among several reported applications, the preparation of novel heterodetic cyclopeptides by an intramolecular side chain‐to‐side chain CuAAC ...

Phytosterol side chain biosynthesis

Lipids, 1974
AbstractThe typical plant sterols contain a substituent at C‐24 of the side chain. This can be a methylene, ethylidene, methyl, or ethyl group; with the last three groups, all possible isomers have been reported in nature. The C‐24 alkyl groups are derived by a transmethylation reaction from methionine.

Stable helical peptoids via covalent side chain to side chain cyclization

Organic & Biomolecular Chemistry, 2008
Peptoids are oligomeric N-substituted glycines with potential as biologically relevant compounds. Helical peptoids provide an attractive fold for the generation of protein-protein interaction inhibitors. The generation of helical peptoid folds in organic and aqueous media has been limited to strict design rules, as peptoid-folding is mainly directed ...

Engineered Ionizable Side Chains

2015
One of the great challenges of mechanistic ion-channel biology is to obtain structural information from well-defined functional states. In the case of neurotransmitter-gated ion channels, the open-channel conformation is particularly elusive owing to its transient nature and brief mean lifetime.

Protein side-chain acetylations

1984
Publisher Summary This chapter discusses the acetylation of protein side-chains. Using preparative gel electrophoresis, it is now possible to prepare the well-defined histone substrates necessary for the studies of the kinetics and mode of action of isolated transacetylases or deacetylases.

Modeling side-chain conformation

Current Opinion in Structural Biology, 1996
Over the past few years, a number of methods for the calculation of side-chain conformations in proteins have been described. More recent studies have considered the effect of combinatorial packing, derivations from idealized rotameric structures and, to a limited extent, backbone flexibility on the quality and efficiency of calculations of protein ...

Peptide nanotube aligning side chains onto one side

Journal of Peptide Science, 2016
A novel pseudo cyclic penta‐β‐peptide composed of a β‐naphthylalanine, two β‐alanines, and a sequence of ethylenediamine‐succinic acid (CP5ES) is synthesized and investigated on peptide nanotube (PNT) formation. When the PNT is formed with the maximum number of intermolecular hydrogen bonds between the cyclic peptides, the sequence enables the ...
