Abstract: During the process of spermatogenesis in rainbow trout, there is extensive acetylation of some histone fractions. A large proportion of the acetyl groups is present in histone IV, and the sites of acetylation in this fraction have been determined. Four lysyl residues in the NH2-terminal region at positions 5, 8, 12, and 16 were found to be acetylated in a fraction of the histone IV molecules. Acetylation of each of these 4 lysyl residues can probably occur independently of the others, at least to some extent. This leads to a complex mixture of ...
