Protein conformation meaning
WebbAnd first, let's start out with the term conformation. And the term confirmation just refers to a protein's folded, 3D structure, or in other words, the active form of a protein. And next we can review what the … Proteins are generally thought to adopt unique structures determined by their amino acid sequences. However, proteins are not strictly static objects, but rather populate ensembles of (sometimes similar) conformations. Transitions between these states occur on a variety of length scales (tenths of Å to nm) and time scales (ns to s), and have been linked to functionally relevant phenomena such as allosteric signaling and enzyme catalysis.

Clearly, interactions between residues that are in contact in the folded state (native interactions) are likely to be important for folding, but, in principle, nonnative interactions may play a role.
WebbProtein structure characterisation is fundamental to biologic development and ongoing quality control, in terms of identification and product homology. Proteins have complex structures which must be … WebbThe study of protein dynamics is most directly concerned with the transitions between these states, but can also involve the nature and equilibrium populations of the states themselves. These two perspectives— kinetics and thermodynamics, respectively—can be conceptually synthesized in an "energy landscape" paradigm: [3] highly populated ...
WebbThe native state of a protein can be distinguished from a molten globule, by among other things, distances measured by NMR. Amino acids widely separated in a protein's sequence may touch or lie very close to one another within a stably folded protein. In a molten globule, on the other hand, their time-averaged distances are liable to be greater.
