== Publication Abstract from PubMed ==
The crystal structure of the type I blue copper protein amicyanin from Thiobacillus versutus has been determined by Patterson search techniques on the basis of the molecular model of amicyanin from Paracoccus denitrificans, and refined by energy-restrained least-squares methods. Amicyanin crystallizes in the trigonal space group P3(2) with unit cell dimensions of a = b = 87.40 A, c = 38.20 A. The asymmetric unit is composed of three independent molecules centred on the crystallographic 3(2) axes. The final R-value is 17.4% for 15,984 reflections to a resolution of 2.15 A. The polypeptide fold in amicyanin is based on the beta-sandwich structure commonly found in blue copper proteins. Nine beta strands are folded into two twisted beta-sheets that pack together with a filling of non-polar residues between them. The geometry of the copper site is similar to that of plastocyanin. There are four ligands, arranged approximately as a distorted tetrahedron, to the copper atom: His54, Cys93, His96 and Met99. One of the copper ligands, His96, is exposed to the surface and lies in the centre of a cluster of seven hydrophobic residues.
