Adaptation of Escherichia coli to the uncoupler of oxidative phosphorylation 2,4-dinitrophenol.
Escherichia coli was found to adapt to the uncoupler of oxidative phosphorylation 2,4-dinitrophenol. The rates of synthesis of 53 proteins were increased following exposure to 2,4-dinitrophenol. Adaptation was accelerated when the cofactor pyrroloquinoline quinone was provided in the growth medium.
متن کاملThe mechanism of uncoupling of oxidative phosphorylation by 2,4-dinitrophenol.
2,4-Dinitrophenol fails to stimulate the breakdown of the soluble high energy intermediate of oxidative phosphorylation isolated from Alcaligenes faecalis extracts. Once the intermediate is broken down, by other reactions, the coupling enzyme is prevented from reassociation with the electron transport particles by 2,4-dinitrophenol. Phosphorylating particles washed with 2,4-dinitrophenol lose c...

متن کاملEXPERIMENTALl ANALYSIS OF PARTITION COEFFICIENT IN Al-Mg ALLOYS
Because the partition coefficient is one of the most important parameters affecting microsegregation, the aim of this research is to experimentally analyse the partition coefficient in Al-Mg alloys. In order to experimentally measure the partition coefficient, a series of quenching experiments during solidification were carried out. For this purpose binary Al-Mg alloys containing 6.7 and 10.2 w...
متن کاملAn axiomatization of partition entropy
The aim of this paper is to present an axiomatization of a generalization of Shannon’s entropy starting from partitions of finite sets. The proposed axiomatization yields as special cases the Havrda-Charvat entropy, and thus, provides axiomatizations for the Shannon entropy, the Gini index, and for other types of entropy used in classification and data mining. Keywords—Shannon entropy, Gini ind...
