Crystallization and preliminary crystallographic data for the azurin mutant End-121 from Pseudomonas aeruginosa

Pseudomonas aeruginosa azurin has been crystallized from a mutant where residues from Met 121 to Lys128 have been deleted from the protein. The crystals form pale-blue well formed prisms in the orthorhombic space group P2₁2₁2₁, with cell dimensions a = 60.79 (5), b = 123.47 (5), c = 187.77 (5) Å. The crystals diffract to 3.0 Å and there are eight molecules in the asymmetric unit.
