    Abstract: 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.

    Abstract: High level expression of heterologous proteins in host cells is frequently limited by the presence of rarely utilized codons, due to depletion of the internal tRNA pool and stalling of translation. This invention provides expression host cells generated by introduction of a vector for the expression of an array of tRNA genes that are rare in the host cells. The modified host cells are capable of efficiently supporting expression of selected recombinant genes which otherwise would be limited by the presence of rare codons.

    Abstract: The present invention relates to a method of screening for constitutively active mutants of a desired eukaryotic MAPK pathway member of a MAPK pathway member, comprising the steps of (a) providing a mutant yeast strain devoid of an upstream kinase; (b) providing a DNA library of different mutants of a mutagenized gene coding for the desired MAPK pathway member; (c) introducing said library into said yeast strain under conditions suitable for activation of the yeast MAPK pathway; (d) detecting an end-point indication for activation of the yeast pathway; and (e) optionally isolating said constitutively activated mutant from selected rescued clones. The invention further relates to isolated constitutively active mutants of the MAPK pathway member, and their various uses particularly, in a method of screening for substances which are inhibitors of a MAPK pathway, and in drug design.
