First, the work marked the beginning of Ochoa's lifelong interest in enzymes.

He further demonstrated that variations in enzymes and proteins, when extreme, are responsible for genetic disease.

A deficiency in digestive enzymes can also cause some types of food intolerances.

This behavior is most common in multimeric enzymes with several interacting active sites.

But injuries to the heart can cause a rise in enzymes that may not necessarily represent a heart attack.

A blood test will look for a rise in cardiac enzymes.

This domain is present one to six times in several enzymes.

Cobalt is found in vitamin B and related enzymes.

This type of inhibition is rare, but may occur in multimeric enzymes.

This may result in different enzymes, called isozymes, with the same function having the same basic name.
