Methods for isolating ω-amino-acids: γ-aminobutyric acid from rye grass

Enzymatic synthesis of chiral γ-amino acids using ω-transaminase.

In this study, we successfully synthesized enantiomerically pure (R)- and (S)-γ-amino acids (>99% ee) using ω-transaminase (ω-TA) through kinetic resolution and asymmetric synthesis respectively. The present study demonstrates the high potentiality of ω-TA reaction for the production of chiral γ-amino acids.

GATMD: γ-Aminobutyric Acid Transporter Mutagenesis Database

Since the cloning of the first γ-aminobutyric acid (GABA) transporter (GAT1; SLC6A1) from rat brain in 1990, more than 50 published studies have provided structure-function information on investigator-designed rat and mouse GAT1 mutants. To date, more than 200 of 599 GAT1 residues have been subjected to mutagenesis experiments by substitution with different amino acids, and the resulting transp...

Short communication:Influence of vacuum packaging and frozen storage time on fatty acids, amino acids and ω -3/ ω-6 ratio of rainbow trout (Oncorhynchus mykiss)

In this study rainbow trout (Oncorhynchus mykiss) fillets were vacuum packed, frozen and stored at -18°C and  the effect of this packaging method on proximate composition, fatty acids and amino acid profile and their changes compared to control conditions during 9 months of storage were studied. The results showed that 18 fatty acids were identified. The unsaturated fatty acid (UFA) were 56.77 ...
