Preliminary survey of carnivore hemoglobin compositions

Abstract

The amino acid differences among 12β chains and 10α chains of carnivore hemoglobins are given. These hemoglobins conform to the substitution rate found for hemoglobins in general. A table compares the differences among knownα-chain sequences when deduced from tryptic peptide 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.
