title: Hemoglobins, XXIX. Sequence analysis of a dimeric hemoglobin (erythrocruorin), CTT-X, of Chironomus thummi thummi (Diptera).
abstract: The amino acid sequences of one of the dimeric hemoglobin components, CTT-X, of Chironomus thummi thummi (Diptera) are given. The sequences were determined by automatic Edman degradation of tryptic peptides and peptides obtained by specific chemical cleavages. CTT-X has two different polypeptide chains, each with 151 amino acid residues. The two polypeptide chains differ only in one amino acid. The sequences are discussed in the light of the sequences of other related heme-proteins.
