The Robotic Hand....
a: Active site ~
b: rigid robot hand
What: "The active site is like the grasping handle of the robot on the assembly line. It can only pick up one part."

A Pocket With A Good Shape
a: Active site ~
b: little pocket of amino acids
What: "The active site is like a little pocket of amino acids that is, since enzymes are highly specific, a lock-key mechanism which allows for the substrate to be added onto the enzyme."

Num Num Num......
a: Active site ~
b: a mouth
What: "The active site is like a mouth -- it chews whatever it touches but can only chew one thing at a time," Kopan explains. "The other site is like a hand -- it's used for holding, and doesn't interfere with the ability of the mouth to chew another object. Maybe one molecule acts as the "hand" serving a meal to the "mouth," which is located on another molecule."

A Rubbery Pocket
a: Active site ~
b: rubbery key hole
What: The common analogy is that an enzyme active size and substrate is like a key and and lock. While this is close, the idea needs to be extended. The key-lock association implies that the molecules in question are as rigid as steel. This is just not the case. Organic molecules are more rubbery than they are rigid. If pull someone tongue you'll see this action. So if you want to realistically visualize organic molecules such as an enzyme and a substrate, try to visualize them as a lock and key made of rubber. They are somewhat specific, but with enough pressure they will deform.

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
