tA generic approach for flavoenzyme immobilization was developed in which the flavin cofactor isused for anchoring enzymes onto the carrier. It exploits the tight binding of flavin cofactors to theirtarget apo proteins. The method was tested for phenylacetone monooxygenase (PAMO) which is awell-studied and industrially interesting biocatalyst. Also a fusion protein was tested: PAMO fused tophosphite dehydrogenase (PTDH-PAMO). The employed flavin cofactor derivative, N6-(6-carboxyhexyl)-FAD succinimidylester (FAD*), was covalently anchored to agarose beads and served for apo enzymeimmobilization by their reconstitution into holo enzymes. The thus immobilized enzymes retained theiractivity and remained active after several rounds of catalysis. For both tested enzymes, the generatedagarose beads contained 3 U per g of dry resin. Notably, FAD-immobilized PAMO was found to be morethermostable (40% activity after 1 h at 60◦C) when compared to PAMO in solution (no activity detectedafter 1 h at 60◦C). The FAD-decorated agarose material could be easily recycled allowing multiple roundsof immobilization. This method allows an efficient and selective immobilization of flavoproteins via theFAD flavin cofactor onto a recyclable carrier.
