The proteins in the hinge ligaments of molluscan bivalves were subjected to chemotaxonomic studies according to their amino acid compositions. The hinge-ligament protein is a new class of structure proteins, and this is the first attempt to introduce chemical taxonomy into the systematics of bivalves. The hinge-ligament proteins from morphologically close species, namely mactra (superfamily Mactracea) or scallop (family Pectinidae) species, showed high intraspecific homology in their compositions. On the other hand, inconsistent results were obtained with two types of ligament proteins in pearl oyster species (genus Pinctada). The results of our chemotaxonomic analyses were sometimes in good agreement with the morphological classifications and sometimes inconsistent, implying a complicated phylogenetic relationship among the species.
根据软体双壳贝类铰合韧带中的蛋白质氨基酸组成进行了化学分类学研究。铰合韧带蛋白是一类新的结构蛋白，这是首次尝试将化学分类学引入双壳贝类的系统分类学中。形态学上相近的物种，即蛤蜊（蛤蜊超科）或扇贝（扇贝科）物种的铰合韧带蛋白，其组成显示出较高的种内同源性。另一方面，珍珠贝属物种的两种韧带蛋白得到了不一致的结果。我们化学分类学分析的结果有时与形态学分类结果一致，有时不一致，这意味着这些物种之间存在复杂的系统发育关系。
