Serum transferrin is a metal-binding glycoprotein, molecular weight ca. 80,000, whose primary function is the transport of iron in the plasma of vertebrates. The X-ray crystallographic structure of diferric rabbit serum transferrin has been determined to a resolution of 3.3 A. The molecule has a beta alpha structure of similar topology to human lactoferrin and is composed of two homologous lobes that each bind a single ferric ion. Each lobe is further divided into two dissimilar domains, and… CONTINUE READING
