Amyloid fibrils of the HET-s — prion form a beta solenoid with a triangular hydrophobic core. Proteins have several layers of structure each of which is important in the process of protein folding. The first most basic level of this structure is the sequence of amino acids themselves. A novel sequence-based method based on the assumption that protein-protein interactions are more related to amino acids at the surface than those at the core.

The interactions of the amino acids will determine what the secondary and tertiary structure of the protein will be. The next layer in protein structure is the secondary structure. The secondary structure includes architectural structures that extend in one dimension. The tertiary structure is the next layer in protein structure. The description of globular protein structures as an ensemble of contiguous closed loops or tightened end fragments reveals fold elements crucial for the formation of stable structures and for navigating the very process of protein folding.

These interactions are important because they lead to the global structure and help create channels and binding sites for enzymes. The last layer of protein structure is the quaternary structure. The folding transition and the functional transitions between useful states are encoded in the linear sequence of amino acids, and a long- term goal of structural biology is to be able to predict both the structure and function of molecules from the information in the sequence.

Proteins are folded and held together by several forms of molecular interactions. The molecular interactions include the thermodynamic stability of the complex, the hydrophobic interactions and the disulfide bonds formed in the proteins.

The biggest factor in a proteins ability to fold is the thermodynamics of the structure. The interaction scheme includes the short-range propensity to form extended conformations, residue-dependent long-range contact potentials, and orientation-dependent hydrogen bonds. The use of energy diagrams and maps are key in finding out when the protein is in the most stable form possible.

The next type of interaction in protein folding is the hydrophobic interactions within the protein. The framework model and the hydrophobic collapse model represent two canonical descriptions of the protein folding process.

The first places primary reliance on the short-range interactions of secondary structure and the second assigns greater importance to the long-range interactions of tertiary structure. Globular proteins acquire distinct compact native con- formations in water as a result of the hydrophobic effect.

The hydrophobic interactions are found to affect time correlation functions in the vicinity of the native state even though they have no impact on same time characteristics of the structure fluctuations around the native state. The types of disulfide bonds are cysteine-cysteine linkage is a stable part of their final folded structure and those in which pairs of cysteines alternate between the reduced and oxidized states.

Proteins can miss function for several reasons. When a protein is miss folded it can lead to denaturation of the protein. Related Stories.
