Tyrosine decarboxylase from Lactobacillus brevis: soluble expression and characterization.
Tyrosine decarboxylase (TDC, EC 4.1.1.25) is an enzyme that catalyzes the decarboxylation of l-tyrosine to produce tyramine and CO2. In this study, a 1881-bp tdc gene from Lactobacillus brevis was cloned and heterologously expressed in Escherichia coli BL21 (DE3). Glucose was discovered to play an important role in the soluble expression of rLbTDC. After optimization, recombinant TDC (rLbTDC) w...
متن کاملPotential Anti-obesity Effects of some Medicinal Herb: In vitro α-Amylase, α-Glucosidase and Lipase Inhibitory Activity
In this study, in vitro inhibitory activity of methanolic and chloroform extracts of some medicinal plants including C. wightii, T. ammi, N. sativa, C. arabica, L. usitatissimum, C. cyminum, and R. Graveolens was evaluated toward α-glucosidase, α-amylase, and lipase comparing with acarbose and orlistat as the standard inhibitors. Our results revealed that both methanolic and chloroform extracts...
متن کاملCharacterization of bacteriocin produced by Lactobacillus plantarum F1 and Lactobacillus brevis
Lactobacillus plantarum F1 and L. brevis OG1 isolated from Nigerian fermented food products, produced bacteriocins that had broad spectrum of inhibition against both pathogenic, food spoilage organisms and various lactic acid bacteria. The test organisms exhibited activities of 6400 and 3200 AU/ml respectively against Escherichia coli NCTC10418 and Enterococcus faecalis EF1, but did not inhibit...
متن کاملPyruvate metabolism in Lactobacillus brevis.
The pyruvate metabolism of LactobaciUus plantarum and Latobacillus arabino8su, which according to Bergey (1948) are identical organisms, has been studied by Rowatt (1951) and Nossal (1952). Both these homofermentative lactobacilli were shown to form 3-hydroxybutan-2-one (acetoin) as the main product of their pyruvate metabolism. No one appears to have studied the metabolism of pyruvate by any o...
متن کامل1,3-Propanediol:NAD+ oxidoreductases of Lactobacillus brevis and Lactobacillus buchneri.
In the cofermentation of glycerol with a sugar by Lactobacillus brevis and Lactobacillus buchneri, a 1,3-propanediol:NAD+ oxidoreductase provides an additional method of NADH disposal. The enzyme has been purified from both L. brevis B22 and L. buchneri B190 and found to have properties very similar to those reported for the enzyme from Klebsiella pneumoniae. The enzymes required Mn2+ and are p...
