Novel arginine deiminase-based method to assay L-arginine in beverages.
A highly selective and sensitive enzymatic method for the quantitative determination of L-arginine (Arg) has been developed. The method is based on the use of recombinant bacterial arginine deiminase (ADI) isolated from the cells of a recombinant strain Escherichia coli and o-phthalaldehyde (OPA) as a chemical reagent. Ammonia, the product of the enzymatic digestion of Arg by ADI, reacts with O...
متن کاملInteraction of L-arginine analogs with L-arginine uptake in rat renal brush border membrane vesicles.
The dibasic amino acid, L-arginine, is a substrate for both nitric oxide synthase (NOS) and arginase and therefore, plays an important role in cell signaling and cell growth. We examined the effects of various NOS inhibitors on L-arginine transport into rat renal brush border membrane (BBM) vesicles. L-Arginine uptake was stimulated in the presence of an inwardly directed Na+ gradient and an im...
متن کاملFlavocytochrome b2-Based Enzymatic Method of L-Lactate Assay in Food Products
L-lactate, a key metabolite of the anaerobic glycolytic pathway, plays an important role as a biomarker in medicine, in the nutritional sector and food quality control. For these reasons, there is a need for very specific, sensitive, and simple analytical methods for the accurate L-lactate measuring. A new highly selective enzymatic method for L-lactate determination based on the use of flavocy...
متن کاملNew Enzymatic Colorimetric Method for the Quantitative Determination of Phenylalanine in Dry-Blood Spots
Phenylketonuria (PKU) is an autosomal recessive disorder, which is characterized by severe mental retardation, microcephaly and seizures. The symptoms of this disease can be prevented if detected soon after birth. Therefore, blood Phenylalanine (Phe) measurement is essential for the early diagnosis, treatment and dietary monitoring of PKU patients. The goal of this research was to introduce a r...
متن کاملMeasurement of Creatinine from Dried Blood spot by Enzymatic Method
Background: DBS on filter paper has been shown as a feasible matrix for collection, transport and analysis of biochemical analytes. Creatinine, is used as a marker of renal function and staging chronic kidney disease (CKD), often requiring repeated testing for drug dosing in patients who undergo dialysis or those who have had arenal transplant. Blood collected and dried on filter paper would be...
