The amino acid sequences of two cuttlefish protamine variants Sp1 and Sp2 have been established from automated sequence analysis and mass spectrometry data. Sp1 (57 residues) and Sp2 (56 residues) have molecular masses of 8410 and 8253 Da, respectively. They are almost identical proteins which differ only by one residue of arginine and the position of two of the serine residues (14 and 37 in Sp1; 13 and 35 in Sp2). With an arginine content of about 77%, cuttlefish protamine is one of the most basic proteins which have ever been characterized and the first typical protamine sequenced in invertebrates. It is closely similar to sperm basic proteins identified in squids but strongly differs from the protamine-like components isolated from the sperm of bivalve molluscs.
