Research output: Contribution to journalArticlepeer-review

Abstract

1. 1. Higher than 16 S arthropod hemocyanin structures are described in terms of a model of the 16 S unit made up of six identical spherical subunits occupying the corners of a regular octahedron. 2. 2. The well-established subunit heterogeneity of arthropod hemocyanins is traced to the fact that the positions allotted for the subunits in the models of higher than 16 S hemocyanins are not all equivalent. 3. 3. The analysis presented provides a basis for the rationalization of the number and relative abundance of subunit types established in 24 S hemocyanin from the crayfish Chrax destructor and 36 S hemocyanin from the scorpion Androctonus australis.
