Publication number: 20130142829Abstract: Cloning and characterization of a TgIF2? kinase from Toxoplasma gondii designated TgIF2K-D illustrates that this protein is related to GCN2, an eIF2? kinase known to respond to nutrient starvation in other organisms. TgIF2K-D is present in the cytosol of both intra- and extracellular Toxoplasma and facilitates translational control through TgIF2? phosphorylation in extracellular parasites. Both a TgIF2K-D knockout parasite and a parasite harboring the TgIF2? mutant (S71A substitution) exhibited loss of eIF2? kinase activity which manifested itself as significant fitness defect. Accordingly, eIF2? phosphorylation and translational control are an important mechanism by which vulnerable extracellular parasites protect themselves which searching for a new host cell. TgIF2K-D is an excellent target for development of compounds and therapies that can be used to treat infections caused by Toxoplasma and other eukaryotic parasites, especially parasites that have high homology or identity to TgIF2K-D.Type: ApplicationFiled: June 6, 2011Publication date: June 6, 2013Applicant: INDIANA UNIVERSITY RESEARCH AND TECHNOLOGY CORPORATIONInventors: William J.

Publication number: 20120058531Abstract: The present invention concerns a new method for the production of 1,3-propanediol comprising culturing a microorganism on a culture medium with high glycerine content. The invention also concerns a new microorganism, or strain of microorganism, adapted for the production of 1,3-propanediol from medium comprising high glycerine content. The invention also concerns an “adapted microorganism” which glycerol metabolism is directed to 1,3-propanediol production, and which is allowed to grow in the presence of a high concentration of industrial glycerine. The invention also concerns a biosourced 1,3-propanediol obtained by the process thereof. Finally the invention concerns the use of the above described biosourced 1,3-propanediol as extender chain in thermoplastic polyurethane, as monomers in polytrimethylene terephtalate and as a component in cosmetics formulations.Type: ApplicationFiled: May 5, 2010Publication date: March 8, 2012Applicant: METABOLIC EXPLORERInventors: Michel Chateau, Jean-Yves Dubois, Philippe Soucaille
