This protein's namesake prosthetic group is synthesized in a pathway that includes 5-aminolevulinic acid as an intermediate.  
This protein's namesake prosthetic group is synthesized in a pathway that includes 5-aminolevulinic acid as an intermediate.  2,3-Bisphosphoglycerate alters its binding ability, but has less interaction with a version of this protein using zeta and epsilon chains. That form is found in the embryo, and separate versions of this protein are expressed in the fetus and in adults. When the glutamic acid at position six of this protein is changed to a valine, a disorder that results in increased malarial resistance occurs. This protein is a tetramer, and defects in this protein yield thalassemia and sickle cell anemia.  For 10 points, name this protein in red blood cells that transports oxygen.
