Latest Patents

Henry Yao's latest patents include innovations related to carotenoid ketolases. The first patent focuses on a mutant carotenoid ketolase, specifically the CrtW carotenoid ketolases, which are useful for the production of astaxanthin. These ketolase genes exhibit improved activity in converting cyclic hydroxylated carotenoid intermediates into astaxanthin. The recombinant expression of these carotenoid ketolases in host cells has enabled increased production of astaxanthin. The second patent presents novel CrtW carotenoid ketolases that are beneficial for producing ketocarotenoids. These genes show low homology compared to previously reported CrtW ketolases. The expression of these carotenoid ketolases in heterologous hosts has facilitated the production of canthaxanthin and astaxanthin, with coexpression experiments leading to enhanced production of the desired ketocarotenoids.
