  • Patent number: 7666658
    Abstract: Nine efficient aldolase antibodies were generated using hapten 2. This hapten combines, in a single molecule, structural components employed for reactive immunization with structural components employed for forming a transition state analog of the aldol reaction. Characterization of two of these antibodies reveals that they are highly proficient (up to 1000-fold better than any other antibody catalyst) and enantioselective catalysts for aldol and retro-aldol reactions and exhibit enantio- and diastereo-selectivities opposite that of antibody 38C2.

  • Publication number: 20090311761
    Abstract: (3R)-3-Hydroxy-?-ionone and (3S)-3-hydroxy-?-ionone are two important intermediates in the synthesis of carotenoids with ?-end group such as lutein, zeaxanthin, ?-cryptoxanthin, and their stereoisomers. Among the various stereoisomers of these carotenoids, only (3R,3?R,6?R)-lutein, (3R,3?R)-zeaxanthin, and (3R)-?-cryptoxanthin are present in commonly consumed fruits and vegetables. There are 3 possible stereoisomers for zeaxanthin, these are: dietary (3R,3?R)-zeaxanthin (1), non-dietary (3S,3?S)-zeaxanthin (2), and non-dietary (3R,3?S;meso)-zeaxanthin (3) which is a presumed metabolite of dietary lutein. Dietary lutein as well as 1 and 3 are accumulated in the human macula and have been implicated in the prevention of age-related macular degeneration. (3R)-?-Cryptoxanthin (4) is also present in selected ocular tissues at a very low concentration whereas its enantiomer (3S)-?-cryptoxanthin (5) is absent in foods and human plasma.

  • Publication number: 20090214475
    Abstract: As the richest source of astaxanthin, a natural antioxidant and coloring agent, the unicellular green alga, Haematococcus pluvialis, is being commercially exploited. A major constraint in the Haematococcus production system, however, is the thick, rigid cell walls associated with astaxanthin-rich cysts (or aplanospores). The thick walls prevent the extraction of cellular materials and consequently reduce the bioavailability of astaxanthin. Using a physical, chemical, or enzymatic method to disrupt the cell wall has proven to be very expensive and also introduce the risk of oxidation of astaxanthin by atmospheric oxygen The present invention provides a novel method for solving this problem by introducing two genetically modified Haematococcus pluvialis mutants. These two mutants, named as D 13-17 and N54-22, contain remarkably reduced amounts of cell wall materials, but retain the growth potential and ability to accumulate astaxanthin as high as the wild type strain.

Another objective of the present invention is to provide novel methods for producing ?-ketoamide reductases that reduce 2-chlorobenzoyl formamide to (R)-2-chloromandelamide with high optical purity, using NADPH as the coenzyme. An enzyme exhibiting high stereoselectivity was purified from a number of Saccharomyces cerevisiae enzymes with 2-chlorobenzoyl formamide-reducing activity, and the biochemical properties of the purified enzyme were analyzed. The analysis of a partial internal amino acid sequence of the purified enzyme revealed that the enzyme may be encoded by the putative open reading frame (ORF) YDL124w reported in the genome analysis. YDL124w was cloned and expressed in E. coli, and was subsequently shown to encode the ?-ketoamide reductase.

  • Patent number: 7252985
    Abstract: 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.

  • Patent number: 7157268
    Abstract: Provided are novel processes for the efficient production of L-epi-2-inosose and epi-inositol which are useful either as various medicines or intermediates for the syntheses of various medicines. In the processes, inexpensive myo-inositol is used as a starting compound which is reacted with a gram-negative bacterium capable of converting myo-inositol into L-epi-2-inosose, and thereby producing L-epi-2-inosose by conversion of myo-inositol into L-epi-2-inosose. A biologically pure culture of Pseudomonas sp. AB 10215 strain is also provided which has a characteristic nature of being capable of converting myo-inositol into L-epi-2-inosose.

  • Patent number: 7122703
    Abstract: The present invention features a chemoselective ligation reaction that can be carried out under physiological conditions. In general, the invention involves condensation of a specifically engineered phosphine, which can provide for formation of an amide bond between the two reactive partners resulting in a final product comprising a phosphine moiety, or which can be engineered to comprise a cleavable linker so that a substituent of the phosphine is transferred to the azide, releasing an oxidized phosphine byproduct and producing a native amide bond in the final product. The selectivity of the reaction and its compatibility with aqueous environments provides for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).
