[ 1 ] - Development and Application of Aqueous Two-Phase Partition for the Recovery and Separation of Recombinant Phenylalanine Dehydrogenase
Aqueous two-phase systems (ATPS) have emerged as a powerful extraction method for the downstream processing of bio-molecules. The aim of this work was to investigate the possibility of utilizing ATPS for the separation of recombinant Bacillus sphaericus phenylalanine dehydrogenase (PheDH). Polyethylene glycol (PEG) and ammonium sulfate systems were selected for our experi...
[ 2 ] - Rapid One-Step Separation and Purification of Recombinant Phenylalanine Dehydrogenase in Aqueous Two-Phase Systems
Background: Phenylalanine dehydrogenase (PheDH EC 1.4.1.20) is a NAD+-dependent enzyme that performs the reversible oxidative deamination of L-phenylalanine to phenylpyruvate. It plays an important role in detection and screening of phenylketonuria (PKU) diseases and production of chiral intermediates as well. The main goal of this study was to find a simple and rapid alternative method for pur...
[ 3 ] - Preliminary Report of NAD+-Dependent Amino Acid Dehydrogenase Producing Bacteria Isolated from Soil
Amino acid dehydrogenases (L-amino acid: oxidoreductase deaminating EC 1.4.1.X) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either NAD+, NADP+ or FAD. These enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...
