ENZYMES AND METHODS FOR PRODUCING OMEGA-3 FATTY ACIDS
The present invention relates generally to the field of recombinant fatty acid synthesis, particularly in transgenic plants. The application describes genes involved in fatty acid synthesis and provides methods and vectors for the manipulation of fatty acid composition of plant oils. In particular, the invention provides constructs for achieving the integration of multiple heterologous genes involved in fatty acid synthesis into the plant genome, such that the resulting plants produce altered levels of polyunsaturated fatty acids. Also described are methods for enhancing the expression of fatty acid biosynthesis enzymes by co-expressing a silencing suppressor within the plant storage organ.
PRODUCTION OF MEVALONATE, ISOPRENE, AND ISOPRENOIDS USING GENES ENCODING POLYPEPTIDES HAVING THIOLASE, HMG-COA SYNTHASE AND HMG-COA REDUCTASE ENZYMATIC ACTIVITIES
The invention features compositions and methods for the increased production of mevalonate, isoprene, isoprenoid precursor molecules, and/or isoprenoids in microorganisms via the heterologous expression of the mvaE and mvaS genes from the organisms Listeria grayi DSM 20601, Enterococcus faecium, Enterococcus gallinarum EG2, and Enterococcus casseliflavus.
METHODS, REAGENTS AND CELLS FOR BIOSYNTHESIZING COMPOUNDS
This document describes biochemical pathways for producing 7-hydroxyheptanoate methyl ester and heptanoic acid heptyl ester using one or more of a fatty acid O-methyltransferase, an alcohol O-acetyltransferase, and a monooxygenase, as well as recombinant hosts expressing one or more of such exogenous enzymes. 7-hydroxyheptanoate methyl esters and heptanoic acid heptyl esters can be enzymatically converted to pimelic acid, 7-aminoheptanoate, 7-hydroxyheptanoate, heptamethylenediamine, or 1,7-heptanediol.
COMPOSITIONS AND METHODS FOR PROTEIN GLYCOSYLATION
Described herein are oligosaccharyl transferases for use in N-glycosylating proteins of interest in vitro and in host cells. Methods for using such oligosaccharyl transferases, nucleic acids encoding such oligosaccharyl transferases, and host cells comprising such oligosaccharyl transferases are also provided herein. Glycoconjugates generated by using such oligosaccharyl transferases are also provided herein.
MULTILAMELLAR LIPID VESICLE COMPOSITIONS INCLUDING A CONJUGATED ANAPLASTIC LYMPHOMA KINASE (ALK) VARIANT AND USES THEREOF
The invention provides compositions including stabilized multilamellar lipid vesicles having crosslinked lipid bilayers (referred to herein as interbilayer-crosslinked multilamellar vesicles or ICMV) and including an ALK variant, pharmaceutical compositions containing vesicles (e.g., ICMV) including an ALK variant, and methods of treatment using such compositions. The invention provides compositions including stabilized multilamellar lipid vesicles with crosslinked lipid bilayers (e.g., an interbilayer-crosslinked multilamellar vesicle or ICMV) containing an Anaplastic lymphoma kinase (ALK) variant as an antigen that is associated with solid tumor cancers.
IMMUNOGENIC BACTERIAL VESICLES WITH OUTER MEMBRANE PROTEINS
Knockout of the meningococcal mltA homolog gives bacteria that spontaneously release vesicles that are rich in immunogenic outer membrane proteins and that can elicit cross-protective antibody responses with higher bactericidal titres than OMVs prepared by normal production processes. Thus the invention provides a bacterium having a knockout mutation of its mltA gene. The invention also provides a bacterium, wherein the bacterium: (i) has a cell wall that includes peptidoglycan; and (ii) does not express a protein having the lytic transglycosylase activity MltA protein. The invention also provides compositions comprising vesicles that, during culture of bacteria of the invention, are released into the culture medium.
