摘要：

1. 1. The sperm nuclei of the marine snail Tegula funebralis (Trochacea, O. Archaeogastropoda) contain five sperm specific proteins. 2. 2. These proteins are of three types: a sperm specific H1, three relatively lysine and arginine-rich molecules, with an amino acid composition similar to H2b histone, and a main component, with a high percentage of arginine (50% of the molecule) and a composition limited to only seven different amino acids. 3. 3. The amino acid content and electrophoretic behaviour of the main protamines from five species of archaeogastropods show many similarities among them, only with slight variations in the lysine content. 4. 4. Here we compare our results with previous data about gastropod sperm proteins. © 1990.
