his-tag-SpyTag-AAO

Aryl alcohol oxidase (AAO) is an enzyme containing flavin-adenine-dinucleotide (FAD). This is the version with SpyTag. In order to be able to construct our multi-enzyme complex, we introduced the SpyTag/SpyCatcher system. We added SpyTag to the N-terminus of each protein through 10 × ELP, which is a oligopeptide linker that does not affect the function of the protein it attaches to, as described in the literature^[1]. So this part can be combined with dCas9-SpyCatcher through covalent isopeptide action, thereby being immobilized on dsDNA. His-tag was added to purify the protein. We use BBa_K3853053 to construct the expression system and to express and to purify the protein.
