Abstract
The amino acid sequence of the protamine isolated from mature sperm nuclei of the ram (Ovis aries) has been established from automated sequence analysis of the S-carboxymethylated protamine. Ram and bull protamines differ only by two point changes and the deletion in bull protamine of the tripeptide Cys39-Arg-Arg41. In mammalian protamines the central region (residues 13-36) consisting mainly of arginine clusters appears to be conserved whereas the N-terminal and C-terminal regions are more variable.Entities:
