| 摘要 |
<p>Genes have been isolated from Rhodococcus and Deinococcus which encode a specific lycopene β-cyclase capable of converting acyclic carotenoids with at least one ψ-end group to the corresponding asymmetric carotenoid containing a single β-ionone ring end group. The genes are new. Transformed host cells expressing the present genes and methods for the bio-conversion of acylic carotenoid substrates to corresponding asymmetric carotenoid are also provided.</p> |
