quaternary structure

基本解释

A great many proteins, especially enzymes, are oligomeric and consequently possess quaternary structure.
很多蛋白质尤其是酶类，是低聚物，因此拥有四级结构。

Antibodies respond to the quaternary structure of proteins so their potential to cross-react with an alloantigen is very low.
抗体对蛋白质的四级结构产生应答，因此它们对同种异型抗原发生交叉反应的能力较弱。
Some proteins consist of more than one polypeptide chain, and the association of these subunits in the protein gives rise to the quaternary structure.
一些蛋白质不只是由一个多肽链组成的，并且这些蛋白质亚基的结构产生了四级结构的。

四级结构
To further improve the classification precision in the protein quaternary structure, we adoptedfour feature extraction methods to research on classification using support vector classification(SVC).
为提高蛋白质四级结构分类精度，应用四种特征值提取方法，基于支持向量机分类进行了研究。
