Publication number: 20090005253Abstract: The invention relates to a novel double hybrid system and to the uses thereof. This system provides, in particular, a tool that enables the detection of the interruption of a protein-protein interaction. The developed system uses transcription interference as a mechanism for detecting a breaking up of interacting protein pairs. The developed double hybrid system can be applied to the screening of molecules enabling the detection of molecules breaking up a protein-protein interaction as well as enabling the identification of alleles lacking in the interaction of proteins involved in the protein-protein interactions.Type: ApplicationFiled: October 24, 2005Publication date: January 1, 2009Applicant: AVENTIS PHARMA S.A.Inventors: Alain Fournier, Ralf Behrens, Silvio Bandiera

Patent number: 7470532Abstract: The present invention relates to a fungal C16/18 fatty acid elongase that is able to catalyze the conversion of palmitate (16:0) to stearic acid (18:0). Specifically, the nucleotide sequence of a Mortierella alpina C16/18 fatty acid elongase is provided (designated as “ELO3”). Methods of increasing microbial oil production, increasing carbon flux into the polyunsaturated fatty acid biosynthetic pathway and increasing the content of polyunsaturated fatty acids by over-expression of the C16/18 fatty acid elongase are described herein. Most desirably, the substrate specificity of the instant ELO3 will be particularly useful to enable accumulation of long-chain polyunsaturated fatty acids in oleaginous yeast, such as Yarrowia lipolytica.Type: GrantFiled: October 19, 2005Date of Patent: December 30, 2008Assignee: E.I. du Pont de Nemours and CompanyInventors: Daniel Joseph Macool, Zhixiong Xue, Quinn Qun Zhu
