Sucrose uptake is driven by the Na+ electrochemical potential in the marine bacterium Vibrio alginolyticus.

چکیده
Na+ was found to be essential for the accumulation of sucrose by Vibrio alginolyticus. Sucrose uptake was completely inhibited by the addition of proton conductor at neutral pH, but not at alkaline pH, where the primary electrogenic Na+ pump generates the Na+ electrochemical gradient. We therefore conclude that sucrose transport is driven by the electrochemical potential of Na+ in this organism.

Intracellular Na+ kinetically interferes with the rotation of the Na(+)-driven flagellar motors of Vibrio alginolyticus.
To understand the mechanism of Na+ movement through the force-generating units of the Na(+)-driven flagellar motors of Vibrio alginolyticus, the effect of intracellular Na+ concentration on motor rotation was investigated. Control cells containing about 50 mM Na+ showed good motility even at 10 mM Na+ in the medium, i.e. in the absence of an inwardly directed Na+ gradient. In contrast, Na(+)-lo...
متن کاملIsolation and molecular identification of Vibrio alginolyticus from cultured marine fish in farms located south provinces of Iran
Bacterial diseases are a major challenge and warning to the development of aquaculture industry. Vibriosis is caused by bacteria of the genus Vibrio, especially Vibrio alginolyticus, in warm and temperate regions, which cause severe damages to the marine fish production economy every year. The aim of the present study was to isolate and identify this bacterium from farmed marine fish with bacte...

Background：Vibrio splendidusVs is an important aquaculture pathogen that can infect a broad host of marine organisms. In our previous study, an antagonistic bacterium Vibrio sp. V33 that possessed inhibitory effects on the growth and virulence of a pathogenic isolate V.splendidusVs was identified. O...
متن کاملPutative channel components for the fast-rotating sodium-driven flagellar motor of a marine bacterium.
The polar flagellum of Vibrio alginolyticus rotates remarkably fast (up to 1,700 revolutions per second) by using a motor driven by sodium ions. Two genes, motX and motY, for the sodium-driven flagellar motor have been identified in marine bacteria, Vibrio parahaemolyticus and V. alginolyticus. They have no similarity to the genes for proton-driven motors, motA and motB, whose products constitu...
متن کاملNa(+)-driven flagellar motor of Vibrio.
Bacterial flagellar motors are molecular machines powered by the electrochemical potential gradient of specific ions across the membrane. Bacteria move using rotating helical flagellar filaments. The flagellar motor is located at the base of the filament and is buried in the cytoplasmic membrane. Flagellar motors are classified into two types according to the coupling ion: namely the H(+)-drive...
