Turns, Which Of The Following Is A Secondary Protein Structure

Turns are short regions of a protein chain that connect two segments of a secondary structure, such as alpha helices or beta strands. They are typically 3-5 amino acids long and are often found at the ends of helices or strands.

Turns are important for the overall structure of a protein, as they allow the chain to change direction and form the compact, folded shape that is necessary for function.There are several different types of turns, each with its own unique structure and function.

The most common type of turn is the beta-turn, which is a tight turn that connects two antiparallel beta strands. Beta-turns are often found in the active sites of enzymes, where they help to position the substrate for catalysis.Other types of turns include the alpha-turn, which connects two parallel alpha helices, and the gamma-turn, which connects a beta strand to an alpha helix.

Turns can also be classified according to their handedness, which refers to the direction of the turn. Right-handed turns are the most common, but left-handed turns also occur.The following are some examples of proteins that contain turns:* Myoglobin: Myoglobin is a small protein that stores oxygen in muscle cells.

It contains several alpha-helices and beta-strands, which are connected by turns.

Hemoglobin

Hemoglobin is a protein that carries oxygen in the blood. It contains four subunits, each of which contains an alpha-helix and a beta-strand. The subunits are connected by turns.

Insulin

Insulin is a hormone that regulates blood sugar levels. It contains two polypeptide chains, which are connected by a turn.Turns are an essential part of protein structure and function. They allow the protein chain to change direction and form the compact, folded shape that is necessary for function.

Final Review

In summary, secondary protein structures provide a deeper understanding of protein function and behavior. From the coiled alpha-helices to the pleated beta-sheets, each structure plays a vital role in shaping the protein’s unique properties.

Remember, the type of secondary structure adopted by a protein is influenced by various factors, including amino acid sequence, environmental conditions, and interactions with other molecules. By unraveling these complexities, we gain valuable insights into the intricate world of proteins.
