- Abstract
The three-dimensional structure of pseudoazurin, a single copper-containing protein from Alcaligenes faecalis strain S-6, has been determined at 2.9 A resolution by X-ray crystallography. The sequences of two other pseudoazurins from Pseudomonas AM1 and Achromobacter cycloclastes may also be accommodated in this structure. The structure, an eight-stranded beta-barrel, resembles closely those of plastocyanin and azurin. It possesses two extra alpha-helices at the C-terminus, whereas azurins have an alpha-helical flap in the middle of their sequences.
