Inactivity of apoperoxidase in indoleacetic acid oxidation and in ethylene formation.
Peroxidase catalyzes oxidatic reactions (in which oxygen is the electron acceptor) as well as the classic peroxidatic reactions (in which hydrogen peroxide is the electron acceptor) (4, 10). There is considerable evidence that the enzyme which catalyzes the oxidatic degradation of the plant growth hormone, indole-3acetic acid, is a peroxidase (8). Recently Yang (12, 13) and Ku et al. (5) have d...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولInactivity of Oxidation Products of Indole-3-acetic Acid on Ethylene Production in Mung Bean Hypocotyls.
The suggestion that indole-3-acetic acid (IAA)-stimulated ethylene production is associated with oxidative degradation of IAA and is mediated by 3-methyleneoxindole (MOI) has been tested in mung bean (Phaseolus aureus Roxb.) hypocotyl segments. While IAA actively stimulated ethylene production, MOI and indole-3-aldehyde, the major products of IAA oxidation, were inactive. Tissues treated with a...
متن کاملOxidation of Indoleacetic Acid by Quackgrass Rhizomes.
The enzymatic oxidlation of 3-indoleacetic aci(l (IAA) which was first described in detail by Tang and Bonner (16, 17), has been observed in several types of plants, e.g., fungi (13), ferns (14), monocotyledonous plants (20), and dicotyledonous plants (16, 17, 19). Although differences have been observed in regard to the enzyme's requirement for a phenolic cofactor, and in the pH optimum, the r...
