Membrane Selection and ISFET Configuration Evaluation for Soil Nitrate Sensing
Successful implementation of site-specific crop management relies on accurate quantification of spatial variation of important factors. Data collection on a finer spatial resolution than is feasible with manual and/or laboratory methods is often required but cost prohibitive. Therefore, there is a need for the development of sensors to more accurately characterize within-field variability. The ...
متن کاملHeterodimers reveal that two arabinose molecules are required for the normal arabinose response of AraC.
AraC protein, which regulates expression of the l-arabinose operon in Escherichia coli, is a dimer whose DNA binding affinity for pairs of DNA half-sites is controlled by arabinose. Here we have addressed the question of whether the arabinose response of AraC requires the binding of one or two molecules of arabinose. This was accomplished by measuring the DNA dissociation rates of wild-type Ara...
متن کاملL-arabinose operon of Escherichia coli
TIG December 2000, volume 16, No. 12 559 Over forty years of research on the L-arabinose operon of Escherichia coli have provided insights into the mechanism of positive regulation of gene activity. This research also discovered DNA looping and the mechanism by which the regulatory protein changes its DNA-binding properties in response to the presence of arabinose. As is frequently seen in focu...
متن کاملNutritional implications of L-arabinose in pigs
The pentose sugar L-arabinose is one of the most abundant components released by complete hydrolysis of non-starch polysaccharides of feed ingredients of vegetable origin. Two studies were conducted to investigate the apparent ileal digestibility and urinary excretion of L-arabinose at dietary inclusion levels of 50 and 100 g/kg, and 25, 50, 75 and 100 g/kg respectively, in pigs. As a reference...
