    摘要： This invention relates to polypeptides having aldolase activity, including pyruvate activity such as, without limitation, HMG and/or KHG aldolase activity, polynucleotides encoding these polypeptides, and methods of making and using these polynucleotides and polypeptides. In some embodiments, the invention is directed to polypeptides having aldolase activity, including pyruvate activity such as, without limitation, HMG and/or KHG aldolase activity, including thermostable and thermotolerant activity, and polynucleotides encoding these enzymes, and making and using these polynucleotides and polypeptides. The polypeptides in accordance with the invention can be used in a variety of pharmaceutical, agricultural and industrial contexts. In some embodiments, the invention provides polypeptides and biosynthetic pathways that are useful in the production of R-2-hydroxy 2-(indol-3ylmethyl)-4-keto glutaric acid (R-MP) and certain stereoisomers of monatin, such as R,R and S, R monatin, and salts thereof, as well as certain stereoisomers of monatin derivatives, such as the R,R and S,R configurations, and salts thereof.

    摘要： The invention provides nitrilases and methods for making and using them, and in one aspect, provides methods for producing enantiomerically pure α-substituted carboxylic acids, such as, for example, α-amino acids and α-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.
