The present invention provides detergent compositions comprising variants of precursor phenol oxidizing enzymes, said precursor being derived from a Stachybotrys species. The precursor enzymes can be, for example, naturally-occurring or recombinant phenol oxidizing enzymes. The variant enzymes, in general, are obtained by modification of a precursor DNA sequence encoding the naturally-occurring or recombinant phenol oxidizing enzyme to generate the substitution of one or more amino acids in the encoded amino acid sequence. Variant enzymes are disclosed having properties which differ from those of their respective precursor enzymes, e.g., altered pH optima and/or phenol oxidizing activity and/or altered stability. The variant enzymes of the present invention are especially useful in detergent formulations, for example, to modify (bleach) the color associated with colored compounds.
A detergent composition comprising one or more surfactants and an enzymatically active variant of a precursor phenol oxidizing enzyme, said precursor being derived from a Stachybotrys species.
A detergent composition comprising one or more surfactants and an enzymatically active variant of a precursor phenol oxidizing enzyme, which precursor phenol oxidizing enzyme has at least 68% identity to the amino acid sequence as disclosed in SEQ ID NO:
A detergent composition comprising a protein having phenol oxidizing activity, which comprises an amino acid sequence having at least 68% and less than 100% identity to the amino acid sequence disclosed in SEQ ID NO:
