Synthesis and Antibacterial activities of some Arabinofuranose-Schiff bases Derivatives [PDF]

open access: yesKirkuk Journal of Science, 2016
As a continuous research for the discovery of new antibacterial agents due to the developing resistance toward conventional antibiotics, we reported a convenient synthetic approach for the preparation of methyl-α-D-arabinofuranoside shiff-bases. A series

The role of gum induced by Fusarium oxysporum Schlecht. Snyd. et Hans. f.sp. tulipae Apt. in tulip bulbs on growth and development of the pathogen

open access: yesPlant Protection Science, 2002
It was showed that gums induced by Fusarium oxysporum f.sp. tulipae in tulip bulbs applied to mineral Czapek-Dox Broth with Bacto Agar (CzDA) medium, containing sucrose substantially stimulated abundant growth of mycelium and sporulation of the pathogen.

A P-type ATPase importer that discriminates between essential and toxic transition metals [PDF]

open access: yes, 2009
Transition metals, although being essential cofactors in many physiological processes, are toxic at elevated concentrations. Among the membrane-embedded transport proteins that maintain appropriate intracellular levels of transition metals are ATP-driven

L-Arabinose 1-dehydrogenase: A novel enzyme involving in bacterial L-arabinose metabolism [PDF]

open access: yesNucleic Acids Symposium Series, 2005
Azospirillum brasiliense converts L-arabinose to alpha-ketoglutarate via five hypothetical enzymatic steps. We purified and characterized L-arabinose 1-dehydrogenase (EC 1.1.1.46) catalyzing conversion of L-arabinose to L-arabino-gamma-lactone as an enzyme involved in the first step of this L-arabinose metabolic pathway.

Cytosine-to-Uracil Deamination by SssI DNA Methyltransferase [PDF]

open access: yes, 2013
The prokaryotic DNA(cytosine-5)methyltransferase M.SssI shares the specificity of eukaryotic DNA methyltransferases (CG) and is an important model and experimental tool in the study of eukaryotic DNA methylation.

Redox linked flavin sites in extracellular decaheme proteins involved in microbe-mineral electron transfer [PDF]

open access: yes, 2015
Extracellular microbe-mineral electron transfer is a major driving force for the oxidation of organic carbon in many subsurface environments. Extracellular multi-heme cytochromes of the Shewenella genus play a major role in this process but the mechanism

L-arabinose and D-xylose: sweet pentoses that may reduce postprandial glucose and insulin responses

open access: yesFood & Nutrition Research, 2021
Background: Diets inducing high fluctuations in plasma glucose levels are linked to type 2 diabetes. L-arabinose and D-xylose have been hypothesized to inhibit intestinal sucrase activity, delay sucrose digestion, and reduce glycaemic and insulinaemic ...

Functional characterization of a highly specific l-arabinose transporter from Trichoderma reesei

open access: yesMicrobial Cell Factories, 2021
Background Lignocellulose biomass has been investigated as a feedstock for second generation biofuels and other value-added products. Some of the processes for biofuel production utilize cellulases and hemicellulases to convert the lignocellulosic ...
