The present application relates to peptides which bind to a target stain, phenol oxidizing enzyme-binding peptide complexes wherein the binding peptide is attached to the C-terminus of the phenol oxidizing enzyme or is inserted or substituted into the phenol oxidizing enzyme. In a preferred embodiment the phenol oxidizing enzyme is a laccase specifically Stachybotrys oxidase B and variants thereof. The invention provides expression vectors comprising the phenol oxidizing enzyme-binding peptide complex as well as host cells comprising the vectors.
