Salinity is a main and common stress which decreases the amount of agriculture products and natural plants in many areas of the world. In this study, the effect of salt stress on three varieties of Lotus corniculatus 'Karaj', 'Jolfa', and 'Ardabil' was investigated. Plants were cultured in hydroponic condition with four NaCl treatments (0, 50, 100, 150 mM). The amounts of proline, glycine betai...

D-Arginine dehydrogenase (DADH) catalyzes the oxidation of D-arginine to imino arginine using FAD as the cofactor. The enzyme is part of a recently discovered two-enzyme complex from Pseudomonas aeruginosa involved in arginine utilization. Function of the enzyme within the organism is unknown. Work on this enzyme has been undertaken to understand the structure as well as its reaction mechanism ...

Molecular dynamics of metabolites are important for their interactions and functions. To understand the structural dependence of molecular dynamics for N-methylated glycines, we comprehensively measured the (13)C and (1)H spin-lattice relaxation times for sarcosine, N,N-dimethylglycine, betaine, and betaine hydrochloride over a temperature range of 178-460 K. We found that the reorientations of...

Michaels, Ruth (Columbia University, New York, N.Y.), and W. A. Corpe. Cyanide formation by Chromobacterium violaceum. J. Bacteriol. 89:106-112. 1965.-The formation of cyanide by a Chromobacterium violaceum strain was studied with growing cultures and with nonproliferating cells grown in complex and chemically defined media. Most of the cyanide was produced during the log-phase growth of the or...

As a first step towards the elucidation of the molecular mechanisms responsible for the utilization of choline and glycine betaine (betaine) either as carbon and nitrogen sources or as osmoprotectants in Sinorhizobium meliloti, we selected a Tn5 mutant, LTS23-1020, which failed to grow on choline but grew on betaine. The mutant was deficient in choline dehydrogenase (CDH) activity, failed to ox...

glycine betaine (gb) is one of the osmotic plant-protecting members that accumulate in response to abiotic stresses. an experiment was, therefore, conducted to test whether gb application at various concentrations (0, 10, 20 and 30 mm) through seed soaking or foliar spray methods would protect cucumber seedlings, subjected to chilling stress. at two true leave stages, after gb treatment, the se...
