Classify each protein example according to its highest level of protein structure. When performing site-directed mutagenesis to test predictions about which residues are essential for protein function, wh amino acid substitution would disrupt protein structure the most.
6. What are the four levels of protein structure? Describe each. What stabilizes each level of structure?
1. Describe at least three factors responsible for denaturation of proteins. Indicate what type of interactions is (are) affected by each factor. (3 points)
11) Proteins may have up to four levels of structure. For each type, describe the kind of bonding interactions that maintain that type of structure. Write whether the bond for that type of structure is covalent or noncovalent. Then specify the type of bond used (for example, hydrogen bond) (16 pts). Bond Type (covalent. or noncovalent Structure Level Specific bond type Prima Seconda Tertiary uaterna
