What is Supersecondary protein structure?

Supersecondary structures, or motifs, are characteristic combinations of a secondary structure 10 to 40 residues in length that recur in different proteins. They bridge the gap between the less specific regularity of a secondary structure and the highly specific folding of a tertiary structure.

Why are Supersecondary structures important?

Supersecondary structures can act as nucleations in the process of protein folding.

What is the difference between Supersecondary protein structure and protein motifs?

Motifs, in a biological sense, are very similar to fashion motifs. They are patterns that repeat in a lot of different places. Supersecondary structures are motifs that are made of several secondary structures.

Why is protein structure important?

Having a protein structure provides a greater level of understanding of how a protein works, which can allow us to create hypotheses about how to affect it, control it, or modify it. For example, knowing a protein’s structure could allow you to design site-directed mutations with the intent of changing function.

What secondary structures do you recognize what is the importance of secondary structures?

The secondary structures play important roles in protein structure and protein folding. We investigate the folding properties of protein by introducing the effect of secondary structure elements. We observed the emergence of several structures with both large average energy gap and high designability.

What is an example of secondary structure in a protein?

A secondary structure of a protein pertains to the folding of a polypeptide chain, resulting in an alpha helix, beta sheet or a random coil structure. Another example of a secondary structure is that of a nucleic acid such as the clover leaf structure of tRNA.

What is a motif vs domain?

Motif is a certain grouping of the super secondary elements of proteins such as alpha helices and beta structures while domain is the functional unit of a protein. Furthermore, motif is a secondary structure while domain is responsible for the tertiary structure of the protein.

What is an unsourced supersecondary structure?

Unsourced material may be challenged and removed. A supersecondary structure is a compact three-dimensional protein structure of several adjacent elements of a secondary structure that is smaller than a protein domain or a subunit.

What is an example of a super secondary structure?

Supersecondary structure. Supersecondary structures can act as nucleations in the process of protein folding. Examples include β-hairpins, α-helix hairpins, and β-α-β motifs . β-sheets (composed of multiple hydrogen-bonded individual β-strands) are sometimes considered a secondary or supersecondary structure.

Do you know the Greek key pattern?

Whether or not you know the name, you’ll recognize the pattern. The ‘Greek key’, also known as the ‘meander’, is a repeating geometric motif that has been used across buildings, decorative arts, jewelry and even clothes for centuries. The pattern can be found in a variety of forms.

What is the origin of the Greek key?

The Greek Key’s exact origins are unclear, with traces of its usage appearing in relics found from Etruscan, Ancient Greek, Ancient Roman and Byzantine cultures. One such early example is the ‘guilloche’ (a pattern created through interlacing curved lines) on the depiction of the Investiture of Zimrilim, dating back to the 18th century BC.
