The protein I selected is called 3B8E; however, it is more commonly known as the Sodium/Potassium Pump or Sodium/Potassium ATPase. This protein has a quarternary structure that consists of an alpha, beta, and gamma subunit. Each subunit is 998, 46, and 29 amino acids long, respectively. The 3B8E contains a large amount of alpha helixes and a few beta pleated sheets, and arranges itself in a globular arrangement.
The 3B8E Sodium/Potassium Pump is found in the cell membrane of every cell in the body of animals. It is responsible for maintaining the gradients of both sodium and potassium. In order to maintain proper functioning, animal cells must have a high gradient of sodium outside the cell and a high gradient of potassium inside the cell. The Sodium/Potassium ATPase uses active transport to pump three sodium ions out of the cell and two potassium ions into the cell. This protein uses a molecule of ATP to acheive this, since it pumps the ions against their gradient. Without this protein, cells would not be able to function at all. This makes the 3B8E, or Sodium/Potassium Pump a very important biomolecule.
