| Outline of Final Research Achievements |
In the first year, we found microbes A and B asymmetrically oxidizing 2,2-diethyl-1,3-propanediol. As a result of optical purity analysis, strain A synthesized (R)-hydroxypropanoate at 65%ee, and strain B synthesized (S)-hydroxypropanoate at 33%ee.
In the second year, we aimed to isolate and characterize the genes coding asymmetrically oxidizing enzyme using heterologous expression system. Several candidate genes were selected through both proteome and whole-genome analysis, and were heterologously expressed. As a result of optical purity analysis, three recombinants exhibited (R)-selectivity. One of the recombinant expressing an alcohol dehydrogenase synthesized (R)-hydroxypropanoate at 90%ee.
