- Laccases are copper-containing phenol oxidizing enzymes that are known to be good oxidizing agents in the presence of oxygen. Laccases are found in microbes, fungi, and higher organisms. Laccase enzymes are used for many applications, including pulp and paper bleaching, treatment of pulp waste water, de-inking, industrial color removal, bleaching in laundry detergents, oral care teeth whiteners, as catalysts or facilitators for polymerization and oxidation reactions, in the textiles industry, and in the food industry.
- Laccases are known to be produced by a wide variety of fungi, including species of the genii Aspergillus, Neurospora, Podospora, Botrytis, Pleurotus, Fornes, Phlebia, Trametes, Polyporus, Stachybotrys, Rhizoctonia, Bipolaris, Curvularia, Amerosporium, Lentinus, Myceliophtora, Coprinus, Thielavia, Cerrena, Streptomyces, and Melanocarpus.

- the systems, compositions, and methods are useful, for example, for processing textiles to affect local color modification on fabrics and garments, including complete, consumer-ready garments.
- Various aspects and embodiments of the systems, compositions, and methods are to be described.
- enzyme refers to a protein that catalyzes a chemical reaction.
- the catalytic function of an enzyme constitutes its "enzymatic activity” or "activity.”
- An enzyme is typically classified according to the type of reaction it catalyzes, e.g. , oxidation of phenols, hydrolysis of peptide bonds, incorporation of nucleotides, etc.
- substrate refers to a substance (e.g., a chemical compound) on which an enzyme performs its catalytic activity to generate a product.
- a "laccase” is a multi-copper containing oxidase (EC 1.10.3.2) that catalyzes the oxidation of phenols, polyphenols, and anilines by single-electron abstraction, with the concomitant reduction of oxygen to water in a four-electron transfer process.
- laccase activity is measured in units/gram (U/g), wherein one unit is defined as the amount of laccase activity required to oxidize 1 nmol of 2,2'-azinobis(3- ethylbenzthiazoline-6-sulfonate; ABTS) substrate per second under conditions of an assay based on the ability of laccase enzyme to oxidize ABTS into its corresponding stable cation radical,
- the radical form is dark green in color with increased absorbance at 420 nm.
- the amount of green color formation is proportional to the amount of laccase activity, and can be compared to a laccase standard curve to determine the absolute amount of laccase activity.
- variant proteins encompass related and derivative proteins that differ from a parent/reference protein by a small number of amino acid substitutions, insertions, and/or deletions.
- the number of different amino acid residues is any of about 1, 2, 3, 4, 5, 10, 20, 25, 30, 35, 40, 45, or 50.

For example, in structural regions that contain an alpha helix or a beta sheet structure, replacement amino acid residues in an analogous sequence maintain the same structural feature. In some embodiments, analogous sequences result in a variant protein that exhibits a similar or improved function with respect to the parent protein from which the variant is derived.
- a "homologous protein” or “homolog” refers to a protein (e.g. , a laccase enzyme) that has a similar function (e.g. , enzymatic activity) and/or structure as a reference protein (e.g. , a laccase enzyme from a different source). Homologs may be from evolutionarily related or unrelated species.
- a homolog has a quaternary, tertiary and/or primary structure similar to that of a reference protein, thereby potentially allowing for replacement of a segment or fragment in the reference protein with an analogous segment or fragment from the homolog, with reduced disruptiveness of structure and/or function of the reference protein in comparison with replacement of the segment or fragment with a sequence from a non-homologous protein.
- wild-type As used herein, wild-type, “native,” and “naturally-occurring” proteins are those found in nature.

- a “signal sequence” refers to a sequence of amino acids bound to the N- terminal portion of a protein, and which facilitates the secretion of the mature form of the protein from the cell.
- the mature form of the extracellular protein lacks the signal sequence which is cleaved off during the secretion process.

- the preparation of a protein derivative is often achieved by modifying a DNA sequence which encodes for the native protein, transformation of that DNA sequence into a suitable host, and expression of the modified DNA sequence to form the derivative protein.
- polypeptide, protein, and peptide refer to a composition comprised of amino acids (i.e., amino acid residues).
- amino acids i.e., amino acid residues

- a textile contains cellulose.
- the term “fabric” refers to a manufactured assembly of fibers and/or yarns that has substantial surface area in relation to its thickness and sufficient cohesion to give the assembly useful mechanical strength.
- Garment refers to a clothing item made from one or more fabrics. Garments typically include fabrics that are already cut to size and sewn or stitched together. Garments may or may not include buttons, eyelets, straps, zippers, hook-and-loop closures, and the like, which can be attached before or after localized color modification.
- color modification refers to a change in the chroma, saturation, intensity, luminance, and/or tint of a color associated with a fiber, yarn, fabric, garment, or non- woven material, collectively referred to as textile materials.
- Color modification encompasses chemical modification to a chromophore as well as chemical modification to the material to which a chromophore is attached. Examples of color modification include fading, bleaching, and altering tint.
- a particular color modification to indigo-dyed denim is fading to a "vintage look," which has a less intense blue/violet tint and more subdued grey appearance than the freshly-dyed denim.
- local color modification refers to color modification, as defined, above, that is performed on only a portion of a fabric or garment.

- the amount of color modification was determined using a chromameter.
- the results obtained at the 30 minute time point are shown in Table 1, wherein a higher L value indicates a higher bleaching level.
- the results obtained at the 60 minute time point were similar, suggesting that the process is essentially complete at 30 minutes.
- Increasing amounts of the laccase/mediator system produced increasing amounts of color modification, in this case a bleaching effect, demonstrating dose response.
- a 10% (w/v) solution of a laccase/mediator system (see Example 1) solution that was freshly made, and a 10% (w/v) solution that was pre-incubated for 45 minutes at room temperature, were separately applied to denim and incubated it for 25 minutes at 40°C.
- the fabric was then rinsed and dried.
- the amount of color modification was determined using a chromameter (Table 2). The color modification was more pronounced when the solution of the laccase/mediator system was pre-incubated prior to application to the fabric.
