Description générale

Iron-carrying proteins conalbumin and serum transferrin are synthesized with identical 19-amino-acid leader sequences that are removed during protein maturation. The leader sequences are presumably involved in secretion of the proteins by endoplasmic reticulum.

Application

Conalbumin (CA) is a monomeric glycoprotein that makes up approximately 13% of the albumin found in egg white. The iron complex of CA is more stable to chemical and physical treatments when compared to the uncomplexed proteins. At near neutral conditions, urea denaturation of CA modifies but does not destroy the iron complex.

The NH2-terminal sequences of egg white conalbumin and chicken serum transferrin were examined and found to be identical. Conalbumin, when synthesized in a rabbit reticulocyte cell-free translation system, was found to contain an NH2-terminal extension of 19 amino acid residues.
