Abstract excerpt
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 di...
