Uses

Useful in the fluorimetric determination of riboflavin

General Description

Riboflavin binding protein (RBP) transports riboflavin through the bloodstream of the laying hen into the eggs, where the vitamin is essential for embryonic growth and development. RBP consists of a single polypeptide chain containing 9 disulfide bonds. It is a glycoprotein containing ~14% carbohydrate, with sugar moieties including galactose, mannose and glucosamine, and is phosphorylated.

Biochem/physiol Actions

Riboflavin binding protein binds to flavokinase and regulates its activity.
