Outline of Final Research Achievements

Azoreductase is NADPH-dependent enzyme that cleaves azo bond in azo dyes. Since NADPH is a high-cost compound, we have sequentially connected an NADPH regeneration system with glucokinase and glucose 6-phosphate dehydrogenase domains to obtain a hybrid azoreductase. The degradation efficiency of azo dyes with the hybrid azoreductase was higher when the domains were connected via flexible linkers. In order to understand the mechanisms of how the linkers contribute to increasing degradation rate of azo dyes, we will track the enzymatic reaction of each domain in the hybrid enzymes using the real-time NMR method.

Academic Significance and Societal Importance of the Research Achievements

代表的な合成染料であるアゾ色素は、生産コストが低いことから、さまざまな繊維の染色において大量利用されている。アゾ色素はその高い化学的安定性により、廃棄にあたっては、凝集沈殿や加温処理などの高いエネルギーコストを必要とする。
本研究では、NADPH再生酵素群をアゾレダクターゼと組み合わせ、より少量の補酵素でアゾ色素を連続分解できるハイブリッド酵素を開発した。このハイブリッド酵素をカードランシートに低コストで固定化することで、工業的な大規模利用への端緒を開いた。また、ハイブリッド酵素による複雑な補酵素再生およびアゾ色素の分解カスケードを、NMR法により精密かつ効率的に観測することにも成功した。
