The complete amino acid sequence of a blue copper protein from Alcaligenes faecalis S‐6 has been determined. This protein is clearly homologous to pseudoazurins in Achromobacter cycloclastes and Pseudomonas AM1, more distantly related to plant plastocyanins, and markedly different from the azurin of Pseudomonas aeruginosa . Yet all of these proteins bind copper, and analogous ligands appear to be involved.
