When analyzingthe amino acid sequences of the plobin proteins shown in this figure,which of the following statements aretrue E7 FS helli Human a globin Hnan ß globn AVAHVDDMPN S PDAvwpPKVKA"GEKVEGA.SDGI LON ca , AT studiu.

O Choose one or more A Mutating the glycine immediately to theright of the E7 position shown in human myoglobin to a tyrosine B. Histidines at positions E7 and F8 are conserved in all three proteins because they are the amino C. Mutating the thireonine just to the right of the F8amino acid in human myoglobin to an aspartic acid would D. It is equally reasonable to assume that amino acid would likely reduce, or eliminate, the correct function of human myoglobin required to coordinate the oxygen binding in the heme cofactor of the given globin molecules almost certainly reduce or eliminate the correct functionality of the protein substitution sites will yield similar results in terms of the structure and function of a changing amino acids at either conservative or nonconservative globin protein

Explanation / Answer

Histidine at position F7 and F8 are conserved in all three proteins because they are the amino acids required to cooordinate the oxygen binding in the heme cofactor of the given globin molecule.
