Oxygen cooperativity Study guides, Class notes & Summaries

You're using anion exchange chromatography to purify a small globular protein. After passing the mixture through the column, you find that your protein did not "stick" to the resin and flowed right through. What is a plausible reason for this to have occurred? Correct Answer-The pH of the solution is close to the isoelectric point. Oxygen binding that affects the cooperatively of hemoglobin is an example of heterotrophic regulation. Correct Answer-False You have determined that a leucin...

A Hill coefficient (nH) of 2 indicates that: A) there is positive cooperativity in ligand binding. B) there are two ligand-binding sites. C) there is negative cooperativity in ligand binding. D) there is positive cooperativity in ligand binding and there are two ligand-binding sites. E) there is negative cooperativity in ligand binding and there are two ligand-binding sites. - A) there is positive cooperativity in ligand binding. A monoclonal antibody differs from a polyclonal antibody in...

E1: Why do proteins fold? - Answer A and B are correct (It is entropically favorable for water & It is enthalpically favorable for the protein) E1: The structural changes in hemoglobin that contribute toward its positive cooperativity for oxygen consist of: - Answer All of the above ( movement of iron into the plane of the heme & movement of a neighboring veiling residue due to strain from changes in the heme & the breaking of a covalent bond with the regulatory molecule BPG

Ligand correct answers A molecule which is reversibly bound by a protein; A small molecule that binds specifically to a larger one; for example, a hormone is the ligand for its specific protein ligand. Induced Fit correct answers Proteins or enzymes may undergo conformational changes when a lignand binds which alters the function of the protein; What do Myoglobin and haemoglobin contain? correct answers They contain a hem prosthetic group which binds oxygen. What does Heme consist of? c...
