Although the tricarboxylic acid (TCA) cycle is essential in almost all aerobic organisms, its precise modulation and integration in global cellular metabolism is not fully understood. Here, we report on an alternative TCA cycle uniquely aimed at generating ATP and oxalate, two metabolites critical for the survival of Pseudomonas fluorescens. The upregulation of isocitrate lyase (ICL) and acylat...

Cinchophen (I) was synthesized from pyruvic acid, aniline and benzaldehyde by Doebner synthesis. Cinchophen acid chloride (II) was synthesised from cinchophen and oxalyl chloride by acylation reaction. The 2phenylquinoline-4-carboxylic acid amide (III) was synthesized from acid chloride and ammonia by simple reaction. The 2-phenylquinoline-4-carboxylic acid amine (IV) was synthesized from cinch...

Pyruvate formate-lyase (acetyl-CoA:formate C-acetyltransferase, EC 2.3.1.54) from anaerobic Escherichia coli cells converts pyruvate to acetyl-CoA and formate by a unique homolytic mechanism that involves a free radical harbored in the protein structure. By EPR spectroscopy of selectively 13C-labeled enzyme, the radical (g = 2.0037) has been assigned to carbon-2 of a glycine residue. Estimated ...

he forage legume cicera chickling (Lathyrus cicera (L.) D.C.) disributed in Mediterranean region is gaining importance in terms f economy and agriculture in Turkey. However, full potential of he legume has to be realized yet due to the presence of neuotoxin, -N-oxalyl-l-a, -diaminopropionoc acid (ODAP) causing athyrism. This study aimed to develop efficient micropropagation ystem using longitud...

Excitatory amino acids and their receptors play an important role in both normal synaptic transmission and excitotoxic-mediated neuronal death. In the present investigation we have prepared a series of glutamate analogs and examined the pharmacological specificity with which they interact with excitatory amino acid receptors. Included within this group of compounds is a potent excitotoxic amino...

Lathyrus sativus L. (Grass pea) is the source for cheap and nutritious food choice in drought and famine susceptible zones in greater part of North India and Africa. The non-protein amino acid β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP) has been known for decades for its potent neurotoxic effect, causing irreversible neurodegenerative disease "neurolathyrism", present in both seed and leaf ...

beta-N-oxalyl-amino-L-alanine, (L-BOAA), an excitatory amino acid, acts as an agonist of the AMPA subtype of glutamate receptors. It inhibits mitochondrial complex I in motor cortex and lumbosacral cord of male mice through oxidation of critical thiol groups, and glutaredoxin, a thiol disulfide oxido-reductase, helps maintain integrity of complex I. Since incidence of neurolathyrism is less com...

samples of grass pea seed (lathyrus sativus) were prepared and analyzed for some chemical composition and as well for their anti-nutritional factors. the rumen degradability coefficients and post ruminal digestibility of dry matter and crude protein of unheated vs. oven heated samples were determined, employing in situ and in vitro techniques. results indicated that grass pea seed contained a c...
