Questions of session 2
Which enzyme that catalyzes the addition of a chemical group to a double bond?What is the name of enzyme that catalyzes the following reaction?
Pyrophosphate + H20 ------- 2 PhosphatesYou are a new researcher in the college lab. You are working with an enzyme that is most active at pH 4.5. Your job is to develop a buffered assay system to study this enzyme. When you look in the chemical cabinet you find that the only chemicals in the lab are the 20 biological amino acids. You run to my office complaining that you need to order more chemicals to make the buffer. I tell you that you have everything you need. As usual, I am correct. Explain why?
Describe why oxygen, which is a substrate for hemoglobin, also functions as an allosteric effector of hemoglobin?
Why is it better that a protein’s native conformation is maintained through weak non-covalent interactions than with stronger covalent interactions?
