摘要： Novel CrtW carotenoid ketolase are provided that are useful for the production of ketocarotenoids. The ketolases genes of the present invention exhibit low homology in comparison to other CrtW ketolases previously reported. Expression of the carotenoid ketolases in heterologous hosts enabled production of canthaxanthin and astaxanthin. Coexpression experiments using divergent crtW genes resulted in increased production of the desired ketocarotenoids.

摘要： The present invention provides methods to engineer microorganisms for the production of C30-aldehyde carotenoids. Specifically, various combinations of crtM, sqs, crtN and crtN2 genes from Staphylococcus aureus and Methylomonas sp. 16a can be co-expressed in transformant hosts, leading to the production of diaponeurosporene monoaldehyde, diapocarotene monoaldehyde, and/or diapocarotene dialdehyde. In a preferred embodiment, the genetically engineered pathway is introduced into a strain of Escherichia coli that has been engineered for the expression of carotenoids, and the C30-carotenoid product is diapocarotene dialdehyde.

摘要： The present invention describes a mutant plasmid replication control region having the ability to convey a phenotype of altered plasmid copy number to the plasmid on which it resides. The mutant replication control region is based on a similar region isolated from the pBBR1 plasmid family. Plasmids containing this replication control region cannot be classed as belonging to any known incompatibility group and thus may co-exist with a broad range of other plasmids in a single host.

摘要： A novel CrtZ carotenoid hydroxylase, isolated from Brevundimonas vesicularis DC263, is provided that is useful for the production of hydroxylated carotenoids. Additionally, a previously identified hypothetical protein from Novosphingobium aromaticivorans has found to have carotenoid hydroxylase activity. Both hydroxylase genes exhibit low homology in comparison to other CrtZ hydroxylases previously reported. Expression of the hydroxylases in heterologous host cells enabled production of hydroxylated carotenoids.
