Difference between iron in hemoglobin and cytochrome

WebMay 7, 2024 · Hemoglobin and myoglobin are two common examples of metalloproteins. They are similar compounds that function to store and transport oxygen in mammalian cells. Another example of a metalloprotein is cytochrome c, which plays a critical role in the electron transport chain to aid in ATP synthesis. WebThe sickle hemoglobin (HbS) occurs as a single nucleotide mutation (GAG/GTG) in the sixth codon of the β-globin gene. This missense mutation results in the substitution of valine for the glutamic acid at the sixth residue of the β-globin chain. This inherited gene occurs in an autosomal dominant fashion.
