Allosteric receptors: from electric organ to cognition.

Annual Review of Pharmacology and Toxicology, 2010
This autobiography covers the past 50 years beginning with the development of the concept of allosteric proteins and its application to pharmacological receptors. It continues with the identification of the nicotinic acetylcholine receptor, the discovery

Phosphate metabolism in the electric organ

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1967
Abstract 1. The concentrations of ATP, ADP, AMP, creatine, creatine phosphate and P i were determined in slices of the main organ of Electrophorus electricus . At rest, they were 0.83, 0.080, 0.012, 18.2, 19.3 and 8.28 μmoles/g wet tissue, respectively. 2.

Electric Organ Discharge Displays during Social Encounter in the Weakly Electric Fish Brienomyrus niger L. (Mormyridae)

, 2010
We investigated the electric organ discharge (EOD) activity of the mormyrid fish Brienomyrus niger during social encounters. The fish were contained in porous ceramic shelters and tested alone and in pairs in an experimental tank designed to restrict ...

The microbe electric: conversion of organic matter to electricity

Current Opinion in Biotechnology, 2008
Broad application of microbial fuel cells will require substantial increases in current density. A better understanding of the microbiology of these systems may help. Recent studies have greatly expanded the range of microorganisms known to function either as electrode-reducing microorganisms at the anode or as electrode-oxidizing microorganisms at the

The Electric Organ of the Skate

There are few, if any, structures in the animal kingdom the origin of which is more difficult to account for than the electric organs of Fishes. Darwin recognised in the electric organs one of the “special difficulties of the Theory of Natural Selection;"

Heart as an Electrical Organ

2018
Definition: The pre-potential where a (gradual) spontaneous depolarization of the sinoatrial nodal cells leads to the generation of action potential that determines the heart rate ().

Electric Organs and Their Control

2006
It has been known for more than 2000 years that some fish can induce painful, numbing sensations when handled. In the late 1600s, it was discovered that this sensation resulted from the production of strong electrical currents produced by the fish (Kellaway 1946).

Interaction of the acetylcholine (nicotinic) receptor protein from Torpedo marmorata electric organ with monolayers of pure lipids.

European Journal of Biochemistry, 1978
Membrane fragments rich in cholinergic (nicotinic) receptor protein were purified from the electric organ of Torpedo marmorata. Their lipid composition is essentially characterized by the prominence of cholesterol, phosphatidylethanolamine and ...

Electric organs: History and potential

Science, 2014
The report “Genomic basis for the convergent evolution of electric organs” (J. R. Gallant et al. , 27 June, p. [1522][1]) is even more interesting when considered in light of the field's historical context.

Hormonal control of sexual differentiation: changes in electric organ discharge waveform.

Science, 1983
Males and females of some mormyrid electric fishes generate electrical pulses that differ in waveform and duration. For one such species, testosterone or dihydrotestosterone induces females and immature males to produce the mature male electric organ ...
