Protein Structure and Function

A protein's specific structure determines how it functions.

Antibodies attach to viruses or bacteria to mark them for destruction by recognizing and binding to a specific foreign substance (antigen).

An enzyme must recognize and bind closely to its substrate, with specific complementary geometric shapes that fit exactly into one another, similar to a key and lock mechanism.
