  • Title: Centipedal hemocyanin: its structure and its implications for arthropod phylogeny.
    Author: Mangum CP, Scott JL, Black RE, Miller KI, Van Holde KE.
    Journal: Proc Natl Acad Sci U S A; 1985 Jun; 82(11):3721-5. PubMed ID: 3858846.
    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.
