Amino Acid Isomerization in the Production of L-phenylalanine from D-phenylalanine by Bacteria.

To establish an advantageous method for the production of l-amino acids, microbial isomerization of d- and dl-amino acids to l-amino acids was studied. Screening experiments on a number of microorganisms showed that cell suspensions of Pseudomonas fluorescens and P. miyamizu were capable of isomerizing d- and dl-phenylalanines to l-phenylalanine. Various conditions suitable for isomerization by...

Chiral discrimination in cyclodextrin complexes of amino acid derivatives: β-cyclodextrin/N-acetyl-L- phenylalanine andN-acetyl-D phenylalanine complexes

In a systematic study of molecular recognition of amino acid derivatives in solid-state β-cyclodextrin (β-CD) complexes, we have determined crystal structures for complexes of β-cyclodextrin/N-acetyl-L-phenylalanine at 298 and 20 K and for N-acetyl-D-phenylalanine at 298 K. The crystal structures for the N-acetyl-L-phenylalanine complex present disordered inclusion complexes for which the distr...

Therapeutic implication of L-phenylalanine aggregation mechanism and its modulation by D-phenylalanine in phenylketonuria

Self-assembly of phenylalanine is linked to amyloid formation toxicity in phenylketonuria disease. We are demonstrating that L-phenylalanine self-assembles to amyloid fibrils at varying experimental conditions and transforms to a gel state at saturated concentration. Biophysical methods including nuclear magnetic resonance, resistance by alpha-phenylglycine to fibril formation and preference of...

The utilization of L- and D-phenylalanine by the rat.

An investigation of the oxidation of phenylalanine has been undertaken in this laboratory in connection with studies of the hereditary defect phenylketonuria (phenylpyruvic oligophrenia), in which the oxidation does not occur in the normal manner. The biochemical defect is accompanied by a profound impairment of mental functioning (2, 3). A knowledge of the details of the oxidation might lead t...

Development of the indicator amino acid oxidation technique in chickens: L-[1-(14)C]phenylalanine infusion dose and phenylalanine oxidation.

Amino acid requirements of broiler breeder chickens are not well known. The indicator amino acid oxidation (IAAO) technique was adapted for use in broiler breeders as a rapid and sensitive method to determine amino acid requirements. During IAAO, phenylalanine oxidation decreases, inversely to the changes in protein synthesis, as the intake of the limiting test amino acid increases from deficie...
