Google Patents US20080227152A1 - In vivo incorporation of unnatural amino acids This striking similarity in protein sequence and structure of the γ-globin genes reflect their concerted evolution from gene duplication and gene conversion.US20080227152A1 - In vivo incorporation of unnatural amino acids Also, a common polymorphism is found in the Aγ gene, where threonine ( Aγ T) replaces isoleucine ( Aγ I) at codon γ75 (HbF-Sardinia). A glycine codon is present in the 5′ or Gγ gene ( HBG2) and an alanine codon characterizes the 3′, or Aγ gene ( HBG1).
γ-Globin is the product of two nearly identical γ-globin genes. Γ-Globin chains differ from β-globin chains in either 39 or 40 amino acid residues, depending on whether a glycine or alanine residue is present at γ136. Structure of the γ-Globin Genes and γ-Globin
The observation that hemoglobin in newborns' erythrocytes was resistant to alkaline denaturation provided the first suggestion that a hemoglobin existed that differed from normal HbA. In this chapter we discuss the clinical and physiological attributes of HbF, HbA 2, embryonic hemoglobins, and their posttranslational modifications. Globin genes are discussed in Chapter 3, hemoglobin switching in Chapter 5, and the structure and function of hemoglobin in Chapter 6 and. All hemoglobins undergo posttranslational modifications forming minor hemoglobins. Hb Gower I (ς 2ε 2), Gower II (α 2ε 2), and Portland (ς 2γ 2) are found in the embryo, fetal hemoglobin (HbF α 2γ 2) is present mainly in the fetus but also in the embryo and adult, whereas HbA (α 2β 2) and HbA 2 (α 2δ 2) are seen primarily in adults. During development, humans express six different hemoglobin types, the products of eight different globin genes (Fig.
