One technique that is used when attempting to solve the crystal structure of a large protein is not to solve the structure of the whole protein itself. Instead, the protein isbroken down into smaller components and the structure of the smaller components is what is solved. Of course, when performing this technique, it must be ensured thatthe process of breaking down the protein into smaller components does not drastically change the structure of the smaller components. With this in mind, where would bethe best locations to cut a protein?At the beginning and end of secondary structures.At beginning and end of protein domains.O At the beginning and end of motifs.At the beginning and end of protein subunits.

Identify the following statements as descriptive of the secondary, tertiary, or quaternary structure of a protein. What types of interactions stabilize each type of structure?(a) The polypeptide chain has a number of bends and twists, resulting in a compact structure.(b) The polypeptide backbone forms a right-handed coil.(c) The four polypeptide chains are arranged in a spherical shape.
In the illustration below, the blue squiggly line represents a protein. Notice that the amino acid that is colored red and the amino acid that is colored black are very close to each other in space, but they are far from each other in the primary structure of this protein. How can you explain why two amino acids that are so far from each other in the primary structure of a protein can be so close together in the tertiary structure of the same protein?
In a subunit of a protein, arginine and aspartic acid have an ionic interaction between their side chains. Part a) If arginine is changed to glutamic acid, would the ionic interaction's stability increase, decrease, or not change and what effect would it have on the protein structure? Explain why. Part b) If arginine is changed to lysine, would the ionic interaction's stability increase, decrease, or not change and what effect would it have on the protein structure? Explain why. Part c) If arginine is changed to isoleucine, would the ionic interaction's stability increase, decrease, or not change and what effect would it have on the protein structure? Explain why.
For the protein given in the attached picture: Write the name of these 5 amino acids corresponding to their abbreviation of 3 letters. Describe precisely how the functional groups in the amino acids are involved in bonding between two successive amino acids in the protein.
The three-dimensional structure of a protein is determined by its primary, secondary, and tertiary structures. Define the primary, secondary, and tertiary structures. What are some of the common secondary structures? What are the forces that hold together the secondary and tertiary structures?
Hydrogen bonding is important at what level of protein structure (primary, secondary, tertiary, or quarternary)? Consider what would happen if there was no hydrogen bonding and just van der Waals in this protein structure. What would you anticipate to happen to its properties? Briefly explain with examples.
Among these amino acid combinations listed above, only the combination of Lys and Glu have side chains with groups that have the greatest ability to stabilize the tertiary structure of a protein. Explain by drawing (a) why Lys and Glu side chain interaction stabilizes the tertiary structure of a protein (b) why the pairs of Glu and Asp & Arg and Pro cannot provide the stability to the protein structure.
You are given a protein solution with a concentration of 0.15 mg/ml. Suppose that we want to prepare a solution containing 100 μg of the protein at a concentration of 1 mg/ml. To achieve this, we will first dry down enough protein solution to obtain 100 μg of proteins. How much solution do we need for drying down? How much volume of H2O do we need to add to the dried protein to obtain the desired concentration?
A protein with a quaternary structure is a multidomain protein. Is this always correct? Explain.
Our growing understanding of how proteins fold allows researchers to make predictions about protein structure based on primary amino acid sequence data. Consider the following amino acid sequence.(a) Where might bends or β turns occur?(b) Where might intrachain disulfide cross-linkages be formed?(c) Assuming that this sequence is part of a larger globular protein, indicate the probable location (external surface or interior of the protein) of the following amino acid residues: Asp, Ile, Thr, Ala, Gln, Lys. Explain your reasoning.
Protein folding is critical for function because the properties of a protein arise from its overall shape and the distribution within that shape of the various amino acid side-chains. Which of the following statements about protein three-dimensional structure are correct? 1) the folding pattern of a protein is ultimately determined by its amino acid sequence. 2) proteins tend to fold in such a way that the hydrophobic amino acids are buried in the interior, while hydrophilic amino acids are exposed at the surface. 3) the chemical interactions within a protein molecule that support its overall folded structure are mostly covalent C-C (carbon to carbon) bonds between amino acid side-chains. 4) the overall folding pattern/shape of a protein molecule is termed its primary structure. 5) during evolution, the three-dimensional structure of a protein is often more strongly conserved than its amino acid sequence. More than one answer might be right
The β-sheet structure is the secondary structure of the protein which is a sideways folded structure of the polypeptide Draw the symbol of the β-sheet structure and Name 2 types of β-sheet and explain the difference
