Title: Respiration-driven Na+ pump and Na+ circulation in Vibrio parahaemolyticus. Author: Tsuchiya T, Shinoda S. Journal: J Bacteriol; 1985 May; 162(2):794-8. PubMed ID: 2985548. Abstract: Sodium circulation in Vibrio parahaemolyticus was investigated. We observed respiration-driven Na+ extrusion from cells by using a Na+ electrode. The Na+ extrusion was insensitive to a proton conductor, carbonyl cyanide m-chlorophenylhydrazone, and sensitive to a respiratory inhibitor, CN-. These results support the idea of the existence of a respiratory Na+ pump in V. parahaemolyticus. The respiration-driven Na+ extrusion was observed only under alkaline conditions.[Abstract] [Full Text] [Related] [New Search]
