The partial sequence of the first 30 residues from the amino-terminus of hemoglobin B in the hagfish,Eptatretus stoutii: Homology with lamprey hemoglobin

Summary The partial sequence of the first 30 residues from the amino-terminus of hemoglobin B in the hagfish,Eptatretus stoutii, has been determined. Considerable homology was found between this sequence and the corresponding sequence of lamprey hemoglobin. Both hagfish and lamprey hemoglobins have an additional segment of 9 residues at the amino-terminus as compared with mammalian hemoglobins.This work was initiated at the University of Texas at Austin, and continued in Dr. Charles Yanofskey's laboratory at Stanford University.
