Diet composition of the electric eel Electrophorus voltai (Pisces: Gymnotidae) in the Brazilian Amazon region.

Journal of Fish Biology, 2020
The diet composition of the electric eel Electrophorus voltai was studied in specimens collected from the River Jari, state of Amapá, eastern Amazon region, Brazil. Analysis on the contents of their stomachs revealed that fish were the most frequent prey

Calcium binding to electroplax membranes from electrophorus electricus

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1978
Abstract 1. Isolated electroplax membranes bound 45Ca with high affinity. 2. Magnesium and some other divalent cations were inhibitory to this phenomenon. Neither sodium nor potassium had any effect. 3. Cholinergic ligands were also inhibitory to calcium binding to the membranes, whereas adrenergic ligands had no effect. 4.

CYCLIC NUCLEOTIDE METABOLISM IN ELECTROPLAX OF ELECTROPHORUS ELECTRICUS

Journal of Neurochemistry, 1977
Abstract— In order to describe the regulation of cyclic nucleotide metabolism in a cholinergic tissue, the properties of cyclic nucleotide phosphodiesterase were determined in electroplax of Electrophorus electricus and compared to those of mammalian brain. Electroplax phosphodiesterase was Mg2+ ‐dependent.

Electrophorus Electricus Acetylcholinesterase

1998
We obtained cDNA clones corresponding to acetylcholinesterase (AChE) from Electrophorus electricus organs. These clones encode catalytic subunits of type T (AChET).

CLINICAL SIGNS, DIAGNOSIS, AND TREATMENT OF LEAD INTOXICATION IN AN ELECTRIC EEL (ELECTROPHORUS ELECTRICUS)

Journal of zoo and wildlife medicine, 2018
An adult, wild-caught electric eel (Electrophorus electricus), weighing 18 kg and measuring 2 m in length, presented with bilateral swellings behind the pectoral fins, lethargy, and anorexia for 2 days. Anesthesia was performed with immersion in tricaine

Soman and receptor-ligand interaction in Electrophorus electroplaques

Biochemical Pharmacology, 1977
Abstract Soman, an organophosphorus cholinesterase inhibitor, interacts irreversibly with both the enzyme acetylcholinesterase and a site similar or identical to the acetylcholine receptor of the intact Electrophorus electricus electroplaque. The Soman-induced inhibition of esterase activity in intact electroplaque is not reversed by washing in ...

Inactivation of Electrophorus electricus acetylcholinesterase by benzenemethane sulfonylfluoride

Archives of Biochemistry and Biophysics, 1978
Abstract Benzenemethane Sulfonylfluoride (329-98-6) is an irreversible inactivator of many esterases including mammalian acetylcholinesterases. However, previous reports indicated that acetylcholinesterase from the electric eel, Electrophorus electricus (EC 3.1.1.7) failed to react with benzenemethane sulfonylfluoride at measurable rates. We report
