Benzoate competes with n-amino acids for n-amino acid oxidase and thus inhibits the activity of the oxidase (l-3). Monosubstituted benzoates, depending upon the substituent, have higher and lower affinities for the oxidase than has benzoate (2). Kojic acid, a Y-pyrone, likewise competitively inhibits the oxidase (4). The present report describes the inhibition of n-amino acid oxidase by certain...

Naturally occurring amino acids were identified as efficient co-catalysts for the alkali metal halide-mediated synthesis of cyclic carbonates from carbon dioxide and epoxides under mild, solvent free reaction conditions. The binary system of histidine/potassium iodide gave an appreciable turnover number of 535 for propylene oxide in 3 h. Detailed studies evaluating a variety of amino acids reve...

Tuberose (Polianthes tuberosa L.) is one of the most important cut flowers in Iran. This research was conducted to investigate the effects of spraying a mixture of amino acids on the physiological and morphological characteristics of tuberose. The experiment was carried out in two successive years (2009 and 2010) using two tuberose cultivars ‘Dezfuli’ and ‘Mahallati’. The experiment was arrange...

chamomile (matricaria chamomilla l.) is one of the most important medicinal plants in iran. the main objective of this study was to determine the effects of organic nutrients on the yield and oil content of chamomile. the experiment was conducted in the spring of 2010. the treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the aminol forte sprays (no spraying or contro...

Isolated cells from leaves of Spinacia oleracea have been maintained in a state capable of high rates of photosynthetic CO(2) fixation for more than 60 hours. The incorporation of (14)CO(2) under saturating CO(2) conditions into carbohydrates, carboxylic acids, and amino acids, and the effect of ammonia on this incorporation have been studied. Total incorporation, specific radioactivity, and po...

Commercially available amino acids mixtures have several advantages such as enhancing assimilation of fertilizer, facilitating uptake of water and nutrients and improving photosynthesis of plants. To investigate the response of gerbera (Gerbera jamesonni L.) flowers ‘Saltino’ to foliar application of a mixture of 19 essential amino acids (0.25, 0.50 and 0.75 mg L-1) and ammonium nitrate (200 mg...
