Conformations

There are some molecules that can be isolated in several conformations, due to the large energy barriers between different conformations.

It allows Relay to target specific protein conformations and suggest personalized treatment.

Altering the chain conformations exposes and conceals different parts of the ubiquitin protein, and the different linkages are recognized by proteins that are specific for the unique topologies that are intrinsic to the linkage.

Although catalysis of the peptide bond involves the C2 hydroxyl of RNA's P-site adenosine in a proton shuttle mechanism, other steps in protein synthesis (such as translocation) are caused by changes in protein conformations.

Antigen specificity is due primarily to the side-chain conformations of the antigen.

Digestive juices break chemical bonds in ingested molecules, and modify their conformations and energy states.

For example, cyclohexane can exist in a variety of different conformations including a chair conformation and a boat conformation, but, for cyclohexane itself, these can never be separated.

However, NMR experiments are able to provide information from which a subset of distances between pairs of atoms can be estimated, and the final possible conformations for a protein are determined by solving a distance geometry problem.

In the case of the SDS-PAGE application, the compound works by disrupting non-covalent bonds in the proteins, and so denaturing them, i.e., causing the protein molecules to lose their native conformations and shapes.

Newman projections of the two conformations of ethane: eclipsed on the left, staggered on the right.

The conformations are hypothesized to be responsible for recruitment of the substrate, its irreversible commitment, and finally processing and translocation into the core particle, where degradation occurs.

The conformations are listed below in order of electrophoretic mobility (speed for a given applied voltage) from slowest to fastest: * Nicked open-circular DNA has one strand cut.

The random coil is not a true secondary structure, but is the class of conformations that indicate an absence of regular secondary structure.

The restoring force is due to the preponderance of wrinkled conformations over more linear ones.

When a chain has many cis bonds, it becomes quite curved in its most accessible conformations.
