    Abstract: The invention provides nitrilases and methods for making and using them, and in one aspect, provides methods for producing enantiomerically pure ?-substituted carboxylic acids, such as, for example, ?-amino acids and ?-hydroxy acids. In one aspect, methods of the invention combine an aldehyde or ketone with a cyanide and ammonia or an ammonium salt or an amine, in the presence of a nitrilase or a polypeptide having nitrilase activity, to stereoselectively hydrolyze the amino nitrile or cyanohydrin intermediate under conditions sufficient to produce the carboxylic acid.

    Abstract: The present invention provides a process for efficiently producing a useful substance; and a microorganism which belongs to coryneform bacteria and which can be used in the process. The present invention provides a process for producing a useful substance by using a microorganism belonging to coryneform bacteria, the microorganism having an ability to take a sugar, which is taken into a cell via a phosphotransferase system (PTS), into a cell via a system other than the PTS, and having an ability to produce a useful substance.

  • Publication number: 20110229937
    Abstract: Isolated nucleic acid molecules, designated MR nucleic acid molecules, which encode novel MR proteins from Corynebacterium glutamicum are described which are involved in biosynthesis of a fine chemical, e.g., methionine biosynthesis. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing MR nucleic acid molecules, and host cells into which the expression vectors have been introduced. The invention still further provides methods of producing methionine from microorganisms, e.g., C. glutamicum, which involve culturing recombinant microorganisms which overexpress or underexpress at least one MR molecule of the invention under conditions such that methionine is produced. Also featured are methods of producing a fine chemical, e.g., methionine, which involve culturing recombinant microorganisms having selected MR genes deleted or mutated under conditions such that the fine chemical, e.g., methionine, is produced.

  • Publication number: 20110229940
    Abstract: The present invention relates to a method for producing an L-amino acid by reacting an enantiomeric mixture of an N-succinyl amino acid with L-succinylase in the presence of N-acylamino acid racemase to specifically hydrolyze the L-form. In particular, the present invention relates to a method for producing an L-amino acid in high yield by using an N-succinyl amino acid whose dissolved concentration is particularly low as a raw material to perform a reaction while precipitating the produced L-amino acid out of the reaction system. The present invention enables efficient production of an L-amino acid having high optical purity, particularly an L-amino acid useful as a raw material for products such as pharmaceutical products and agricultural chemicals.

  • Patent number: 8008262
    Abstract: ?-peptide regions of polypeptides can serve as structural mimics of ?-helices in wild type proteins. Because ?-helices of one protein often bind to a target protein in a biological pathway, a polypeptide that contains a helical ?-peptide region can be used to disrupt this type of protein-protein binding. As a result, polypeptides that contain a helical ?-peptide region can be used to treat conditions involving this type of protein-protein binding, such as viral infections and cell proliferation.
