Guaiacol is a universal substrate for all peroxidases and its use in a simple colorimetric assay has wide applications. However its exact binding location has never been defined. Here we report the crystal structures of guaiacol bound to cytochrome c peroxidase (CcP). A related structure, with phenol bound, is also presented.
