The complete amino acid sequence of giant multisubunit hemoglobin from the polychaete Tylorrhynchus heterochaetus.

T Suzuki, T Gotoh.   

Abstract

The extracellular hemoglobin from the polychaete Tylorrhynchus heterochaetus is a "giant," multisubunit protein with an apparent molecular weight of 3.37 X 10(6), and consists of two types of subunits: a "monomeric" chain (chain I) and a disulfide-bonded "trimer" of chains IIA, IIB, and IIC. We reported the amino acid sequences of chains I, IIB, and IIC previously (Suzuki, T., Yasunaga, H., Furukohri, T., Nakamura, K., and Gotoh, T. (1985) J. Biol. Chem. 260, 11481-11487). The sequence of chain IIA has now been determined. Chain IIA consists of 146 amino acid residues with a heme group and has a molecular weight of 17,236. All of the constituent chains of Tylorrhynchus hemoglobin appear to be homologous with those of vertebrate hemoglobins and contain heme. Distal (E7) His, distal (E11) Val, and proximal (F8) His are all conserved in the four chains. Phylogenetically, chain IIA appears more closely related to the monomeric chain I than to either of the other "trimeric" chains IIB and IIC. This is the first giant extracellular hemoglobin to be sequenced completely.
