| Abstract | Gamma-amino butyric acid (GABA) possesses several physiological functions such as neurotransmission, induction of hypotension, diuretic and tranquilizer effects. Production of GABA-enriched products by lactic acid bacteria has been a focus of different researches in recent years because of their safety and health-promoting specifities. In this study, glutamate decarboxylase (gad) gene of a local strains Lactobacillus casei was identified and cloned. In order to clone the gad gene from this strain, the PCR was carried out using primers designed based on conserved regions. The PCR product was purified and ligated into PGEM-T vector. Comparison of obtained sequences shows that this fragment codes the pyridoxal 5'-phosphate binding region. This strain could possibly be used for the industrial GABA production and also for development of functional fermented foods. Gad gene manipulation can also either decrease or increase the activity of enzyme in bacteria. |
