An enzyme of unknown function within the amidohydrolase superfamily was discovered to catalyze the hydrolysis of N-6-substituted adenine derivatives, several of which are cytokinins. Cytokinins are a common type of plant hormone and N-6-substituted adenines are also found as modifications to tRNA. Patl2390, from Pseudoalteromonas atlantica T6c, was shown to hydrolytically deaminate N-6-isopente...

This study aimed to investigate the effects of certain nutrient medium types enhanced with plant-growth regulators on direct inductionof somatic embryogenesis in vegetative strains produced and propagated from a tissue culture Digitalis purpurea. The results showthat MS was superior other tested media-B5, LS, 5C01—in terms days required initiate somaticembryogenesis induction rate. In contrast,...

Photocatalytic benzyl alcohol (BA) oxidation to value-added chemicals by semiconductors has attracted massive attentions due its industrial interest. In this work, Z-scheme heterojunction photocatalysts composed of FAPbBr3 nanocrystals (NCs) and WO3 with different morphologies are prepared. Benefiting from the strong redox potential morphological engineering, photocatalyst exhibits an outstandi...

A novel Ba(II) complex, [BaL2Cl2] (1) (L = pyridine-2-carboxaldehyde-2-phenylacetic acid hydrazone), has been synthesized using BaCl2, pyridine-2-carboxaldehyde and 2-phenylacetohydrazide as raw materials. The structure of 1 has been determined by elemental analysis and X-ray single-crystal diffraction technique. X-ray structural analysis showed that the Ba(II) complex (1) crystallizes in monoc...

The investigation aimed to study the effect of foliar application chemicals on plant canopy, vegetative growth and flowering, as well overall appearance Ixora chinensis plants grown in pot. Application salicylic acid, benzyl adenine silicon at different concentrations significantly influenced growth, pigments compared untreated (control). Plants treated with 10 mg/l 20 acid showed significant i...

who recommends artemisinin-based combination therapies (acts) as the most effective choice to treat malaria. for developing transgenic plants with high accumulation of artemisinin (by introducing genes encoding enzymes which regulate the biosynthetic pathway of artemisinin), an efficient protocol for tissue culture and plant regeneration is necessary. in the present study, leaf explants of arte...

A new flavooxidase is described from a Bjerkandera arthroconidial anamorph. Its physicochemical characteristics, a monomeric enzyme containing non-covalently bound flavin adenine dinucleotide (FAD), and several catalytic properties, such as oxidation of aromatic and polyunsaturated aliphatic primary alcohols, are similar to those of Pleurotus eryngii aryl-alcohol oxidase (AAO). However, it also...

The metabolism of the rat esophageal carcinogen A/-nitrosomethylbenzylamine (NMBzA) was studied using microsomes prepared from liver and esophageal mucosa of untreated male Sprague-Dawley rats. NMBzA was extensively metabolized to benzaldehyde, benzyl alcohol, and formaldehyde by hepatic microsomes. The rate of metabolism at the benzyl moiety was 10-fold higher than that at the methyl moiety. M...

The influence of the support (Al2O3, CeO2, TiO2) in oxidation benzyl alcohol (BA) to benzaldehyde on Ir-based catalysts was investigated by ATR-IR spectroscopy tandem with modulation excitation (ATR-IR-MES) at working conditions catalysts. ATR-IR-MES unveiled dissociative adsorption BA and formation adsorbed transient alkoxy species (C6H5CH2O) be key for high catalytic performance. These were d...
