title: Amino acid sequence of Sp23, a structural protein of the spermatophore of the mealworm beetle, Tenebrio molitor.
abstract: In this paper we present the amino acid sequence of Sp23, a structural protein of the spermatophore of the mealworm beetle (Tenebrio molitor). This is the first report of the primary structure of a spermatophorin. The protein is rich in proline (24%), relatively rich in tyrosine (9%) and glutamine (10%), and does not contain sulfur-containing amino acids. In the carboxyl-terminal half of the protein a peptide motif is repeated which is similar to a repetitive motif in a group of dipteran chorion proteins.
