Abstract
The present invention relates to a process wherein one or more dye precursors, e.g., indole, are provided to a textile and converted by one or more enzymes, e.g., an oxidizing enzyme, to provide the textile with a dye, e.g. indigo. At least the oxidizing enzyme is a hybrid enzyme including a binding domain that is suitable to bind the enzyme to the textile and/or increase the affinity of the enzyme for the textile, in particular, a cellulose binding domain (CBD).
Claims19
A process for dyeing a textile including a cellulosic material, comprising the following steps:
- a) providing indole or an indole derivative to at least part of said textile;
- b) providing at least an oxidizing enzyme to at least part of said textile, whereby said at least part of textile includes said indole or indole derivative and said oxidizing enzyme;
- c) converting at least part of said indole or indole derivative to indigo or indigo derivative, thereby dyeing at least part of said textile;
- wherein said oxidizing enzyme is an oxidizing hybrid enzyme comprising a cellulose-binding domain (CBD).
A process for dyeing a textile that includes one of collagen, chitin, chitosan, polyester, a synthetic polymeric material, comprising the following steps:
- a) providing indole or an indole derivative to at least part of said textile;
- b) providing at least an oxidizing enzyme to at least part of said textile, whereby said at least part of textile includes said indole or indole derivative and said oxidizing enzyme;
- c) converting at least part of said indole or indole derivative to indigo or indigo derivative, thereby dyeing at least part of said textile;
- wherein said oxidizing enzyme is an oxidizing hybrid enzyme comprising a binding domain selected from collagen-binding domain, chitin-binding domain, chitosan-binding domain, polyester-binding domain, a binding domain for a synthetic polymeric material.
A hybrid enzyme comprising an oxidizing enzyme or a tryptophanase enzyme, and at least one binding domain selected from a cellulose-binding domain (CBD), a collagen-binding domain, a chitin-binding domain, a chitosan-binding domain, a polyester-binding domain, a synthetic polymeric material-binding domain.
