Preliminary crystallographic data for a basic copper-containing protein from cucumber seedlings

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.
