Abstract

The oxygen carrier hemocyanin occurs in the blood of Scutigera coleoptrata, a uniramous arthropod, as well as the crustaceans and chelicerates. The native polymer appears to be composed of substructures having the same size and electron-dense image as those of other arthropod hemocyanins but assembled into a unique multiple and arranged in a unique configuration. The simplest explanation of these findings is that the arthropod hemocyanins have a common origin, exemplifying a derived (as opposed to primitive) character shared by each of the three living groups.

摘要

氧载体血蓝蛋白存在于单枝节肢动物蚰蜒以及甲壳类动物和螯肢动物的血液中。天然聚合物似乎由一些亚结构组成,这些亚结构的大小和电子致密图像与其他节肢动物血蓝蛋白的亚结构相同,但组装成独特的多重结构并以独特的构型排列。对这些发现最简单的解释是,节肢动物血蓝蛋白有共同的起源,这体现了三个现存类群共有的一个衍生(而非原始)特征。
