What does stop mean in amino acids?
The “stop” or “terminator” residue is an amino acid that is incorporated in the peptide chain when a protein is made. It’s not part of the protein’s primary structure or amino acid sequence. Protein synthesis doesn’t end when the stop residue is incorporated; rather, it’s the completion of the protein and the linking of the two or more peptide chains together that marks the end of the protein’s synthesis.
What does stop mean in chemistry?
A stop signal in an amino acid is basically a chemical group that prevents the amino acid from combining or linking to another one. There are several ways to stop an amino acid: the first one is a simple bond between two of its atoms, for example an amide group (-CO-NH2) or a thioester (-COSH), that stops the chemical reaction and avoids the combination of two amino acids. The second is the attachment of a simple group to the amino group of the amino acid
What does stop mean in science?
The word “stop” in a chemical context refers to the ability of one chemical to inhibit the activity of another. If A is able to stop B from happening, it can be called an inhibitor. There are two ways to describe the stop function of an amino acid. One is the ability of an amino acid to act as an enzyme inhibitor and prevent the reaction catalyzed by an enzyme. This is called an “inhibitory activity.” The second way is to prevent the
What does stop mean in baseball?
In baseball, a stop is an at bat in which the player gets no hits. A batter gets a stop when they fail to hit the ball in the air, reach base safely, or score a run. If a runner reaches base safely, but the ball is hit into fair territory or an outfielder throws the ball to the infielder, the batter is credited with a single.
What does stop mean in protein?
Amino acids are the building blocks of protein. Nine of the 20 amino acids that make up the building blocks of proteins are considered ‘stop’ or ‘termination’ amino acids. These amino acids are called stop because they signal the end of one protein and the beginning of another. If an elongation amino acid is added to the end of a protein, the resulting protein will be longer. Addition of methionine will terminate the protein. This property of terminating protein synthesis is
