The domains outlined in red represent carrier proteins.

They can be either a channel or a carrier protein.

KLH is the most widely employed carrier proteins for this purpose.

KLH is an effective carrier protein for several reasons.

Attack of ammonia via an amidotransferase enzyme releases the carrier protein.

Each carrier protein is designed to recognize only one substance or one group of very similar substances.

Research has correlated defects in specific carrier proteins with specific diseases.

Each carrier protein, even within the same cell membrane, is specific to one type or family of molecules.

Other specific carrier proteins also help the body function in important ways.

The iron is released into the plasma to be recirculated by a carrier protein called transferrin.
