title: Amino acid sequence of the coelomic C globin from the sea cucumber Caudina (Molpadia) arenicola.
abstract: The sequence of a globin from a marine invertebrate, the sea cucumber Caudina (Molpadia) arenicola (Echinodermata), is reported. This globin, chain C, is one of four major globins found in coelomic red cells in this organism and is the second to be sequenced. Chain C consists of 157 residues, is amino-terminally acetylated, and has an extended amino-terminal region. This globin shares a 60% sequence identity with the other sequenced C. arenicola globin, D chain (Mauri et al., Biochem. Biophys. Acta 1078, 63-67, 1991), but has a 93.6% identity with a globin from another sea cucumber, Paracaudina chilensis (Suzuki, Biochem. Biophys. Acta, 998, 292-296, 1989).
