Histones are basic proteins associated with the DNA of eukaryotic cells, and appear to have a fundamental role in the organisation of the chromosomes of higher organisms [l-3] . Comparative primary sequence information is available for most of the major histones (for recent review see [3]). However the complete primary structure of histone H2B is known only for calf thymus [4] . Here we present the primary sequence of histone H2B isolated from brown trout (Sulmo truttu) testes. Comparison of the primary structure of histone H2B between trout testes and calf thymus indicates that the trout histone H2B differs by deletion of two residues, and substitution of seven other residues. All observed changes except one have occurred in the N-terminal half of histone H2B.
