Abstract

Saving energy in the living life is a pressing need today when the restriction on the earth environment is strict with energy consumption. We examine a lighting environment at the present residence from the illuminance and lighting method. As a result, we show that EL (Elector luminescent) and LED (Light Emitting Diode) has a possibility to become a source of light which is abundant and energy conservation in the next generation.

Abstract

Adaptation of the response to stimuli is a fundamental process for all organisms. Here, we show that the adaptation enzyme CheB methylesterase of Escherichia coli assembles to the ON state receptor array after exposure to the repellent l-isoleucine and dissociates from the array after adaptation is complete. The duration of increased CheB localization and the time of highly clockwise-biased flagellar rotation were similar and depended on the strength of the stimulus. The increase in CheB at the receptor array and the decrease in cytoplasmic CheB were both ~100 molecules, which represents 15 to 20% of the total cellular content of CheB. We confirmed that the main binding site for CheB in the ON state array is the P2 domain of phosphorylated CheA, with a second minor site being the carboxyl-terminal pentapeptide of the serine chemoreceptor. Thus, we have been able to quantify the regulation of the signal output of the receptor array by the intracellular dynamics of an adaptation enzyme. [ABSTRACT FROM AUTHOR]
