Removal of Cysteine (an Aliphatic Amino Acid) by Natural Clinoptilolite
Amino acids have been extensively used in several processes of the pharmaceutical and food industries. Treatments for the recovery and reuse of the wastewaters generated from these processes are few and little known. This work aims at studying the influence of different variables on the sorption of L-cysteine, contained in aqueous solutions, on clinoptilolite mineral. L-Cysteine (Cys) was s...
متن کاملCharacterization of Two Aromatic Amino Acid Aminotransferases and Production of Indoleacetic Acid in Azospirillum Strains
Sunnnary-Experiments were made to quantify indole-3-acetic acid (IAA) excreted by different wild type strains of Azospirilhun spp. The microorganisms produce IAA, during the late stationary growth phase and show a significant increase in IAA production when tryptophan is present in the medium. Under these conditions with the A. brusilense strain UAP 14, we observed two aromatic amino acid amino...
متن کاملRole of amino acid transporters in amino acid sensing.
Amino acid (AA) transporters may act as sensors, as well as carriers, of tissue nutrient supplies. This review considers recent advances in our understanding of the AA-sensing functions of AA transporters in both epithelial and nonepithelial cells. These transporters mediate AA exchanges between extracellular and intracellular fluid compartments, delivering substrates to intracellular AA sensor...
متن کاملAmino acid requirements and amino acid supply in the sheep.
The special features of nitrogen metabolism in ruminants, which stem from the extensive breakdown and synthesis of dietary protein in the rumen (see Hungate, 1966), imply the absence of a specific dietary requirement for essential amino acids. Nevertheless, there is considerable theoretical and practical interest in defining the amino acid requirements of ruminant tissues in animals of known nu...
متن کاملPreliminary Report of NAD+-Dependent Amino Acid Dehydrogenase Producing Bacteria Isolated from Soil
Amino acid dehydrogenases (L-amino acid: oxidoreductase deaminating EC 1.4.1.X) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either NAD+, NADP+ or FAD. These enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...
