Abstract

From the marine mollusc, Patella granatina, a histone has been isolated. Its primary structure has been established and it has been designated histone H2Bpatella. It consists of a polypeptide chain of 121 amino acids. 2. In the carboxy-terminal two thirds of the molecule there is a highly degree of sequence homology to the corresponding region in calf histone H2B with identical residues in 95% of the positions. 3. In the N-terminal 22 amino acids histone H2Bpatella differs considerably from the mammalian histone H2B and it is shorter by four residues.

摘要

从海洋软体动物石榴石笠贝中分离出了一种组蛋白。其一级结构已确定，并被命名为组蛋白H2Bpatella。它由一条121个氨基酸的多肽链组成。2. 在该分子羧基末端的三分之二区域，与小牛组蛋白H2B的相应区域具有高度的序列同源性，95%的位置存在相同残基。3. 在N端的22个氨基酸中，组蛋白H2Bpatella与哺乳动物组蛋白H2B有很大差异，且少了四个残基。
