A highly selective biosynthetic pathway to non-natural C50 carotenoids assembled from moderately selective enzymes
Synthetic biology aspires to construct natural and non-natural pathways to useful compounds. However, pathways that rely on multiple promiscuous enzymes may branch, which might preclude selective production of the target compound. Here, we describe the assembly of a six-enzyme pathway in Escherichia coli for the synthesis of C50-astaxanthin, a non-natural purple carotenoid. We show that by judi...
متن کاملSyntheses of carotenoids involving the ylidenebutenolide structure.
In our previous papers (1, 2), we reported the synthesis of retinoidal 4 ylidenebutenolide (Scheme 1), the method of which involves Wittig reaction of the unstable conjugated anhydride (1) with the acetyl phosphorane (2). Attempts to extend the conjugation by use of the retinoidal 4-ylidenebutenolide (3) or (4) were unfortunately frustrated by the instability of intermediates. In addition, the ...
متن کاملCarotenoids in ornamental fish farming
The aquaculture industry has grown dramatically in recent years, with a multimillion-dollar market. There are a variety of freshwater fish, marine fish, mollusks, and ornamental fish cultivated in this industry. The pigment and coloring of ornamental fish are important characteristics for marketing. In edible fish, carotenoids are responsible for the pigmentation of body tissue, while in ...
متن کاملSuperlative carotenoids.
A selection of carotenoids beyond normal appearance or properties has been presented at the 16(th) International Symposium on Carotenoids. Some of the exceptional compounds shown at the conference cannot be reproduced in this proceeding since they have not yet been published. In addition, editorial space limitation does not allow illustrating all of the previously mentioned carotenoids.
متن کاملCarotenoids and cardiovascular health.
Cardiovascular disease (CVD) is the main cause of death in Western countries. Nutrition has a significant role in the prevention of many chronic diseases such as CVD, cancers, and degenerative brain diseases. The major risk and protective factors in the diet are well recognized, but interesting new candidates continue to appear. It is well known that a greater intake of fruit and vegetables can...
