To directly evaluate the role of increased ornithine decarboxylase (ODC) and polyamines in mouse skin carcinogenesis, we used bovine keratin 5 (K5) and keratin 6 (K6) promoter elements to direct the expression of antizyme (AZ) to specific skin cell populations. AZ is a multifunctional regulator of polyamine metabolism that inhibits ODC activity, stimulates ODC degradation, and suppresses polyam...

The oil palm (Elaeis guineensis Jacq.) fruit primary abscission zone (AZ) is a multi-cell layered boundary region between the pedicel (P) and mesocarp (M) tissues. To examine the cellular processes that occur during the development and function of the AZ cell layers, we employed multiple histological and immunohistochemical methods combined with confocal, electron and Fourier-transform infrared...

In crude cell-free extracts of Azotobacter chroococcum, nitrogenase was much less sensitive to irreversible inactivation by O2 than was the purified enzyme. When nitrogenase was partially purified by anaerobic discontinuous sucrose-density-gradient centrifugation, O2-tolerance was retained. This preparation was considerably enriched in four polypeptides, three of which were derived from the Mo-...

A field experiment was conducted during 2018–19 and 2019–20 at the research farm of ICAR-Directorate Rapeseed-Mustard Research, Bharatpur, Rajasthan to evaluate effect organic inorganic nitrogen sources on yield, water productivity, system productivity economics maize (Zea mays L.)-mustard [Brassica juncea (L.) Czern.] cropping system. The in split-plot design with recommended levels fertilizer...

Bacterial redox protein azurin (azurin for short, or Az) belongs to a class of copper-containing proteins known as cupredoxins. We report here our detailed studies and findings on prospects for application of Az for treatment of cancer through various approaches of nanotechnology. We first present the structure and characteristics of Az protein molecule, its electronic properties and its electr...

Know a day’s Computer system become essential and it is most commonly used in every field of life. The computer saves time and use to solve complex and extensive problem quickly in an efficient way. For this purpose, software programs are develop to facilitate the works for administrator, offices, banks etc. so Quality is the most important factor as it mostly defines CUSTOMER SATISFACTION whic...

Vela, Gerard R. (School of Aerospace Medicine, Brooks Air Force Base, Tex.), and Orville Wyss. Radiation resistance of soil Azotobacter. J. Bacteriol. 89:1280-1285. 1965.-Quantitative recovery of Azotobacter from soils subjected to gamma-radiation from a cobalt-60 source showed the soil populations to be much more highly resistant than isolates from such cultures grown on laboratory media. Even...

Antizyme (AZ) is a protein with 228 amino acid residues that regulates ornithine decarboxylase (ODC) by binding to ODC and dissociating its homodimer, thus inhibiting its enzyme activity. Antizyme inhibitor (AZI) is homologous to ODC, but has a higher affinity than ODC for AZ. In this study, we quantified the biomolecular interactions between AZ and ODC as well as AZ and AZI to identify functio...

the high yield depends on high dry matter production per unit area. azotobacter bio-fertilizer experiment to investigate the effect on the index, total dry matter accumulation and pishtaz and chamran wheat cultivars in 2005 was conducted in the faculty of agriculture, lorestan university. experiment, a split-plot randomized complete blocks design with four replicates were tested. treatments con...

It has been reported (Gunter, 1954) that Mg++ prolongs the viability of various microorganisms suspended in potassium phosphate buffer, and that celLs of Azotobacter are singularly affected by MgSO4. It was previously observed (Goucher and Kocholaty, 1954) that MgSO4 is required for the oxidation of several organic compounds by whole cells of Azotobacter agile. Data presented in this communicat...
