Two new histone H2B variants have been isolated from sperm cells of the sea urchin Psammechinus miliaris. They have been designated sperm histone H2B(1) Psammechinus and sperm histone H2B(2) Psammechinus. Both histones are highly homologous to the previously described sperm histones from Parechinus angulosus (Strickland et al. (1977) Eur. J. Biochem. 77, 263--275 and 277--286). The amino acid sequences of the Ps. miliaris sperm histones, though highly homologous, are not identical to the amino acid sequence derived from the codon sequence of a histone H2B gene, characterized from the same organism by Birnstiel et al. ((1977) Nature 266, 603--607).
从海胆沙钱精子细胞中分离出了两种新的组蛋白H2B变体。它们被命名为沙钱精子组蛋白H2B(1)和沙钱精子组蛋白H2B(2)。这两种组蛋白与先前描述的角海胆精子组蛋白高度同源（斯特里克兰等人，(1977)《欧洲生物化学杂志》77卷，263 - 275页以及277 - 286页）。沙钱精子组蛋白的氨基酸序列虽然高度同源，但与从组蛋白H2B基因密码子序列推导出来的氨基酸序列并不相同，该基因是由伯恩斯蒂尔等人从同一生物体中鉴定出来的（(1977)《自然》266卷，603 - 607页）。
