Abstract

A copper-containing protein, plastocyanin from poplar leaves, has been crystallized in the oxidized (i.e Cu(II)) state. The deep blue crystals are rhombic prisms with space group P212121 and cell dimensions a=29·6A, b=46·9A, c=57·6 A. The molecular weight is 10,500. There are four molecules of protein in the unit cell, and hence there is one molecule in the asymmetric unit.

Abstract

A basic protein with a molecular weight of approximately 10,100 and having a single atom of Type I copper has been isolated from cucumber seedlings. The oxidized, cupric, form of the protein has been crystallized as thin olive-green plates with space group P 2 1 2 1 2 1 and cell dimensions a = 30.8 A, b = 45.6 A and c = 66.6 A. There is one protein molecule per asymmetric unit.
