Bacterial genomic DNA is highly organized into one or few compacted bodies known as nucleoid, which is composed of DNA, RNA and several DNA-binding proteins. These DNA-binding proteins require essential alterations in their expression during stationary phase of growth in order to respond to stressful environmental conditions. Dps (DNA-binding protein from starved cells) is one of such DNA-bindi...

Stationary phase is the stage when growth ceases but cells remain metabolically active. Several physical and molecular changes take place during this stage that makes them interesting to explore. The characteristic proteins synthesized in the stationary phase are indispensable as they confer viability to the bacteria. Detailed knowledge of these proteins and the genes synthesizing them is requi...

Mouse erythroleukemia (MEL) cells contained galactosyltransferase (GT), fucosyltransferase (FT), and A/-acetylglucosaminyltransferase activities and only a small amount of sialyltransferase activity. Dimethyl sulfoxide-treated MEL cells, un dergoing erythrodifferentiation, contained twice as much GT, 20 to 50% less FT, and approximately the same amount of Nacetylglucosaminyltransferase activiti...

influence the driving force. Thermodynamic quantities determined from homologous series retention throughout the entire composition range may lead to a better understanding of the driving force and fundamental retention mechanism that results from the inherent differences in chromatographic solvation between acetonitrile and methanol. Tan and co-workers (11) showed that stationary-phase composi...
