STRUCTURE domain in proteins

A STRUCTURE domain in a protein is a specific part of the protein that has a distinct shape and function. Think of it as a specialized "building block" or "module" within the larger protein. These domains help the protein perform particular tasks, like binding to other molecules or catalyzing reactions. Different domains can be combined in various ways to give the protein its unique capabilities. Overall, the structure domain contributes to the protein’s stability and function by maintaining its three-dimensional shape and facilitating specific interactions.
