The globins are a related family of proteins, all of which have similar primary and tertiary structure (amino acid sequence and folding). These proteins all incorporate the globin fold, a series of eight alpha helical segments. Two prominent members of this family include Myoglobin and Hemoglobin, which both bind the heme (also Haem) prosthetic group. Both these proteins are reversible oxygen binders.… (More on Globin)
