Preliminary survey of carnivore hemoglobin compositions. Conclusions

The amino acid differences among 12 beta chains and 10 alpha chains of carnivore hemoglobins are given. These hemoglobins conform to the substitution rate found for hemoglobins in general. A table compares the differences among known alpha-chain sequences when deduced from tryptic petide compositions and when taken from actual sequences. Among the carnivore hemoglobins studies, tryptic peptide compositions are about 14 % low in giving the number of sequence differences.
