The Fine Structure of the Electric Organ of the Electric Eel and Torpedo Ray
Electric organs or tissues have been described in seven families of fish (Dahlgren, 1), but all of them have several features in common. The tissues occur as a series of more or less flattened plates or electroplaques, each of which consists of a nucleated cytoplasmic syncytial plate having a relatively large surface area. The plates are supplied with nerve endings on one surface only. On one o...
متن کاملMolecular structures of acetylcholinesterase from electric organ tissue of the electric eel.
Three purified molecular forms of acetylcholinesterase (EC 3.1.1.7) with sedimentation coefficients of 18 S, 14 S, and 11 S were studied by analytical ultracentrifugation and electron microscopy. The three species have molecular weights of (1.1 +/- 0.1) x 10(6), (7.5 +/- 1.5) x 10(5), and (3.35 +/- 0.25) x 10(5), respectively. Electron micrographs reveal that the 18S and 14S forms are asymmetri...
متن کاملPre-steady-state charge translocation in NaK-ATPase from eel electric organ
Time-resolved measurements of charge translocation and phosphorylation kinetics during the pre-steady state of the NaK-ATPase reaction cycle are presented. NaK-ATPase-containing microsomes prepared from the electric organ of Electrophorus electricus were adsorbed to planar lipid bilayers for investigation of charge translocation, while rapid acid quenching was used to study the concomitant enzy...
متن کاملPurification by affinity chromatography of the molecular forms of acetylcholinesterase present in fresh electric-organ tissue of electric eel.
An acetylcholinesterase inhibitor-Sepharose conjugate was prepared by coupling a derivative of the powerful acetylcholinesterase inhibitor, N-methylacridinium, to CNBr-activated Sepharose. Use of this conjugate permitted direct purification, by affinity chromatography, of the two molecular forms of acetylcholinesterase, 14 and 18 S, present in fresh electric organ tissue. The purified 14S and 1...
متن کامل1068 Electric Organ In
The electric organ of G. carapo is formed by linearly arrayed electroplaques which lie in four tubes on each side of the fish. In one tube the electroplaques are innervated on their rostral surfaces, in the others on the caudal. Both surfaces of each electroplaque produce spikes, and either can be excited alone by a suitably oriented externally applied stimulating current. The innervated surfac...
