Abstract: The present invention provides genes that encode the N-acetyl-(R,S)-?-amino acid acylases. The N-acetyl-(R,S)-?-amino acid acylases were isolated and purified from bacterial cells and the nucleotide sequences were determined. A host, such as Escherichia coli, was used to construct a high-expression system for these genes. The N-acetyl-(R)-?-amino acid acylase produced by Burkholderia sp. AJ110349 (FERM BP-10366) includes, for example, the protein having the amino acid sequence shown in SEQ. ID. NO. 8. The gene encoding this enzyme includes, for example, the DNA having the nucleotide sequence as shown in SEQ. ID. NO. 7. The N-acetyl-(S)-?-amino acid acylase produced by Burkholderia sp. AJ110349 (FERM BP-10366) includes, for example, the protein having the amino acid sequence shown in SEQ. ID. NO. 10.

Abstract: The present invention provides a method for producing an L-amino acid using a bacterium of the Enterobacteriaceae family, particularly a bacterium belonging the genus Escherichia or Pantoea, wherein said bacterium has attenuated expression of a gene encoding a toxin of a bacterial toxin-antitoxin pair.
Abstract: According to the process for producing amino acid or salt thereof in the present invention, in the adsorption step, an amino acid-containing aqueous solution is fed into a pressure tight column so that a free amino acid is adsorbed on a carbonate-type anion exchange resin packed in the pressure tight column. Subsequently, in the elution step, eluent liquid containing a hydrogen carbonate ion and/or a carbonate ion is injected into the pressure tight column in a pressurized state to elute the amino acid adsorbed on the anion exchange resin and simultaneously to regenarate the anion exchange resin into the carbonate-type. In the case of purifying an acidic amino acid, an aqueous ammonium carbonate solution is employed as the eluent liquid. In the case of purifying a neutral amino acid, an aqueous carbonic acid solution, an aqueous hydrogen carbonate solution, an aqueous ammonium hydrogen carbonate solution or an aqueous ammonium carbonate solution is employed as the eluent liquid.
