title: [3 types of sperm proteins in eukaryotes].
abstract: Basic spermal proteins of various species of hydrobionts attributed to Pisces and Cephalopoda are studied. It is established that chromatin of nine species referring to two Cypriniformes families includes the somatic histones. Histone H1 of Cypriniformes is attributed to the lysine-rich type histones and contains 35% mol. of lysine and 0.7% mol. of tyrosine. Chromatin of 14 species of fish referring to nine families of the percoid fish superorder includes protamines similar to salmin, a typical protamine of salmon. The amino acidic analysis of protamine from the sandre sperma has shown that it contains 59% mol. of arginine and no tyrosine. Chromatin of three species from squid superorder referring to Cephalopoda includes gametones -- proteins differing from histones and protamines both in the electrophoretic mobility and amino acidic composition (75% mol. of arginine, 3% mol. of tyrosine).
