Definition

A process in which the activity of a protein is changed by the binding of a molecule at a site other than the active site, leading to a change in its shape and function.

Example

Allostery plays a crucial role in the regulation of enzyme activity.

Conversation

Have you ever heard of allostery?

I think so, but I'm not entirely sure what it means.

It's really interesting; it refers to how a molecule can change shape and function.

Oh, that makes sense! I love learning about how things work at that level.

Root Explanation

Allostery → It is formed from "allo-" (from Greek "allos", meaning other) and "stereos" (meaning solid or three-dimensional). The term describes a process in biochemistry where the binding of a molecule at one site on a protein affects the function of the protein at a different site, hence the concept of 'other' ('allo-') affecting the 'solid' structure ('stereos').

Memory Tip

Think of 'other' ('allo-') affecting the 'solid' structure ('stereos') of a protein, which helps you remember that allostery involves changes in protein function due to binding at a different site.
