title: A corrected primary structure for dog-fish Scylliorhinus caniculus protamine Z3.
abstract: We have redetermined the primary structure for dog-fish protamine using automated amino-acid sequencing associated to mass spectrometry techniques and report, on the basis of these findings, that the previously published amino-acid sequence is incorrect. The correct protamine sequence is 37 amino acids long and differs from the original published sequence by the C-terminal hexapeptide Arg32-Gly-Arg-Arg-Ser-Arg37.
