Protein Domain Definition Biology

Domains may exist in a variety of biological contexts where similar domains can be found in proteins with different functions.

Protein domain definition biology. Proteins sharing more than a few common domains are encoded by members of evolutionarily related genes comprising gene families. What is the example of protein. Domains are distinct functional and or structural units in a protein.

One domain may appear in a variety of different proteins. Protein description is a material that includes amino acids carbohydrates and carbon hydrogen oxygen nitrogen and sometimes sulfur and is included in many diets. Like the ph domain above many domains are not unique to the protein products of one gene but instead appear in a variety of proteins.

Each domain forms a compact folded three dimensional structure. Molecular evolution uses domains as building blocks and these may. A structural domain is an element of the protein s overall structure that is stable and often folds independently of the rest of the protein chain.

Usually they are responsible for a particular function or interaction contributing to the overall role of a protein. Proteins are organic molecules that are present in living organisms.
