Description générale

Research area: CELL SIGNALING

Phenylalanine dehydrogenase is a member of a large family of amino-acid dehydrogenases, which includes glutamate dehydrogenase, alanine dehydrogenase, leucine dehydrogenase, lysine €-dehydrogenase, and meso-a,€-diaminopimelate D-dehydrogenase. The three known gene sequences are octomers. It has a two-domain, three-dimensional structure.

Actions biochimiques/physiologiques

Phenylalanine dehydrogenase (PheDH) is considered an effective enzyme to estimate the quantity of phenylalanine to distinguish phenylketonuria (PKU) disease.Moreover, it is utilized for the production of optically pure l-phenylalanine, a key component of the artificial sweetener aspartame. L-Phenylalanine dehydrogenase is a NAD+-dependent oxidoreductase that catalyzes the reversible, oxidative deamination of L-phenylalanine, which results in its degradation. L-Phenylalanine dehydrogenase is used to study phenylalanine metabolism and phenylalanine, tyrosine, and tryptophan biosynthesis.

Définition de l'unité

One unit will oxidize 1.0 μmole of L-phenylalanine per min at pH 10.5 at 30 °C in the presence of β-NAD.

Phenylalanine dehydrogenase catalyzes the reversible, pyridine nucleotide-dependent oxidative deamination of L-phenylalanine to form phenylpyruvate and ammonia. We have characterized the steady-state kinetic behavior of the enzyme from Rhodococcus sp. M4 and determined the X-ray crystal structures of the recombinant enzyme

NAD+-dependent phenylalanine dehydrogenases were purified 1,500- and 1,600-fold, and crystallized from Sporosarcina ureae SCRC-R04 and Bacillus sphaericus SCRC-R79a, respectively. The purified enzymes were homogeneous as judged by disc gel electrophoresis. The enzyme from S. ureae has a molecular weight of

This study is concerned with further development of the kinetic locking-on strategy for bioaffinity purification of NAD(+)-dependent dehydrogenases. Specifically, the synthesis of highly substituted N(6)-linked immobilized NAD(+) derivatives is described using a rapid solid-phase modular approach. Other modifications of the
