The present invention relates to compositions and a process in the field of self-cleaning system using digestive proteins. One composition includes a substrate, a digestive protein capable of decomposing a stain molecule, and a link moiety bound to both said digestive protein and said substrate. An alternative composition includes a digestive protein capable of decomposing a stain molecule and a coating substrate wherein said digestive protein may be dispersed in said coating substrate. The process claim includes binding a substrate to a surface and forming a linker moiety between a digestive protein and said substrate.

1. A composition for removing stains from a solid surface comprising: a digestive protein capable of decomposing stain forming molecules,a substrate applied to the solid surface, anda linker moiety bound to an outer surface of said substrate and an active group of said digestive protein, said linker moiety between said protein and said substrate and covalently linking said protein to a surface of said substrate,said digestive protein forming a layer on a surface of said substrate such that the digestive protein is surface exposed for reaction with a stain. 2. The composition according to claim 1, wherein the digestive protein comprises lysozymes, proteases, lipases, cellulases, glycosidases, amylases. 3. The composition according to claim 1, wherein said stain forming molecules are selected from the group consisting of proteins, oils, fats, and carbohydrates. 4. The composition according to claim 1, wherein said substrate comprises one or more surface active groups selected from alcohol, thiol, aldehyde, carboxylic acid, anhydride, epoxy, and ester. 5. The composition according to claim 1, wherein a decomposition product of said stain molecule decomposed by said digestive protein is removable by water-rinsing. 6. The composition according to claim 1, wherein said substrate comprises paint, and polymers. 7. A process for self-cleaning, comprising: binding a substrate to a surface; andforming a linker moiety between an active group of a digestive protein and said substrate so as to form the composition of claim 1. 8. The process according to claim 7, wherein said substrate comprises one or more selected from the group consisting of alcohol, thiol, aldehyde, carboxylic acid, anhydride, epoxy, and ester. 9. The process according to claim 7, wherein said surface is selected from the group consisting of metal, glass, paint, plastic, and fabrics. 10. The process according to claim 7, wherein said active group is selected from the group consisting of alcohol, amine, thiol, and carboxylic acid. 11. The process of claim 7, wherein the degradation of a stain molecule by said digestive protein occurs in a dry environment. 12. The process of claim 11, wherein the end product of said degradation is removable by water or rain.
