Effects of dicyclohexylcarbodi-imide on proton translocation coupled to fumarate reduction in anaerobically grown cells of Escherichia coli K-12. 1976

S J Gutowski, and H Rosenberg

The addition of dicyclohexylcarbodi-imide to anaerobic cells of Escherichia coli K12 decreases both the observed extent of proton translocation coupled to fumarate reduction by endogenous substrates and the t 1/2 of proton re-entry after such translocation, but does not affect fumarate uptake. Dicyclohexylcarbodi-imide also inhibits fumarate reductase activity in cell extracts.

UI	MeSH Term	Description	Entries
D011522	Protons	Stable elementary particles having the smallest known positive charge, found in the nuclei of all elements. The proton mass is less than that of a neutron. A proton is the nucleus of the light hydrogen atom, i.e., the hydrogen ion.	Hydrogen Ions,Hydrogen Ion,Ion, Hydrogen,Ions, Hydrogen,Proton
D002234	Carbodiimides	Compounds with the general formula RN	Carbodiimide
D004024	Dicyclohexylcarbodiimide	A carbodiimide that is used as a chemical intermediate and coupling agent in peptide synthesis. (From Hawley's Condensed Chemical Dictionary, 12th ed)	DCCD
D004579	Electron Transport	The process by which ELECTRONS are transported from a reduced substrate to molecular OXYGEN. (From Bennington, Saunders Dictionary and Encyclopedia of Laboratory Medicine and Technology, 1984, p270)	Respiratory Chain,Chain, Respiratory,Chains, Respiratory,Respiratory Chains,Transport, Electron
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
