title: Identification of the globin chain and the amino acid residue responsible for polymerization of bullfrog (Rana catesbeiana) hemoglobin with iodo[14C]acetamide.
abstract: The bullfrog (Rana catesbeiana) major hemoglobin dissociates into its constituent globin chains (alpha and beta) which are separated by Sulfopropyl-Sephadex C-25 column chromatography after alkylation with iodo[14C]acetamide. Each globin chain has two cysteine residues and those of the beta-globin chain in the tetramer are preferentially alkylated with iodoacetamide.
