Macromolecular complexes of acrylamide and sodium acrylate copolymer with microelements, including Cu(II), may form at preparation crop protection stimulation compositions, where the serves as an adhesive, water-retaining film-forming agent. Preparations for production also contain amino acids that protect plants under stressful conditions (cold, dry, etc.). Carboxylic groups copolymer, carboxy...

material remaining after dialysis was lyophilized and then hydrogenated with 10% platinum on Darco. After hydrolysis and analysis for amino acids, the yields of alanine and of craminobutyric acid were found to be at least 20 and 35% of the theoretical values, respectively. Keratosulfate from shark cartilage was allowed t’o react with alkali in the presence of Adams catalyst (5) and hydrogen. At...

L-Aspartate β-decarboxylase from Acinetobacter radioresistens (ArASD) has been modified to convert 3-methylaspartic acid into 2-aminobutyric acid, which activated a novel process for biosynthesis of acid. However, the is limited by low activity ArASD. Here, ArASD was significantly improved modification based on sequence alignment and structural analysis. The 38th residue speculated be key regul...

BACKGROUND Hypotheses regarding the nature of channel modulation by volatile anesthetics have focused primarily on "membrane actions" of anesthetics and more recently on direct actions of volatile agents on receptor proteins themselves. With the recognition that many channels are subject to modulation by intracellular enzymes, such as protein kinases and phosphatases, and recent demonstrations ...

1. Animal studies show that cardiac vagal tone can be modified by gamma-aminobutyric acid neurons acting at several sites in the central nervous system. The present study has attempted to determine whether similar control exists in humans by using midazolam, a benzodiazepine. Benzodiazepines exert their main actions on the central nervous system by interacting co-operatively at the gamma-aminob...

The present study was undertaken to determine whether gamma-aminobutyric acid in the paraventricular nucleus contributes to the regulation of cardiovascular function. Blood pressure and heart rate were recorded and plasma catecholamines were measured in conscious rats receiving microinfusions of either artificial cerebrospinal fluid or a gamma-aminobutyric acid antagonist, bicuculline methiodid...

Streptococcus thermophilus strain B59671 is a Gram-positive lactic acid bacterium that naturally produces a broad-spectrum bacteriocin, thermophilin 110, and is capable of producing gamma-aminobutyric acid (GABA). The complete genome sequence for this strain contains 1,821,173 nucleotides, 1,936 predicted genes, and an average G+C content of 39.1%.
