protein code (1taq)

Question 1: What is the name of the protein?

Question 2: What does the protein do? E.g., if it an enzyme of the Citric Acid Cycle – you must state which metabolic process it is involved in and the reaction step it catalyzes.
Question 3: What are the structural features of the protein?
Question 4: What are 2 features of your protein's structure that makes it different or similar to adult hemoglobin?
Question 5: Based on the structural properties of your protein, how resistant (or sensitive) would your protein be to heat denaturation, and why?

Answer #1

ans 1. Myoglobin

ans 2. Myoglobin is an iron-containing protein in muscle that receives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the oxygen is used in cellular respiration to produce energy.

and 3. Myoglobin is a monomeric protein that has 154 amino acids residues. It consists of eight α-helices connected through the turns with an Oxygen binding site. It has a globular structure. Each myoglobin molecule has one heme prosthetic group located in the hydrophobic cleft in the protein.

and 4. Both haemoglobin and myoglobin carry hee prosthetic group. . Myoglobin binds 1 oxygen molecule whereas Hemoglobin binds 4. Hemoglobin can bind to Carbon dioxide which myoglobin can't do.
