Complete amino acid sequence of human hemopexin, the heme-binding protein of serum.


We have determined the complete primary structure of human hemopexin, a plasma beta-glycoprotein that specifically binds one heme with high affinity and transports it to hepatocytes for salvage of the iron. Human hemopexin (Mr approximately equal to 63,000) consists of a single polypeptide chain containing 439 amino acid residues with six intrachain… (More)
