Abstract excerpt
Four variants of human beta globin in which the Trp at position 37 has been replaced with a Tyr, Ala, Gly, or Glu have been expressed in Escherichia coli. These globins have been combined with normal human alpha chains and heme to form tetrameric hemoglobin molecules. A technique for the preparation of alpha chain dimers, which are cross-linked between their alpha99 lysine residues, has been developed, and these...
