Roles of the Respiratory Na+ Pump in Bioenergetics of Vibrio alginolyticus (1988)

Tokuda, Hajime, Asano, Makoto, Shimamura, Yoshiki, Unemoto, Tsutomu, Sugiyama, Shigeru, Imae, Yasuo

Bioenergetic characteristics of Na+ pump-defective mutants of a marine bacterium Vibrio alginolyticus were compared with those of the wild type and revertant. Generation of membrane potential and...

Partial Purification and Properties of Respiratory Chain-Linked L-Glycerol 3-Phosphate Dehydrogenase from a Marine Bacterium, Vibrio alginolyticus (1981)

UNEMOTO, Tsutomu, HAYASHI, Maki, HAYASHI, Makoto

Respiratory chain-linked L-glycerol 3-phosphate (G3P) dehydrogenase [EC 1.1.99.5] of marine bacterium, Vibrio alginolyticus, was extracted from the membrane fraction by treatment with Tween 20, and...

NADH: Quinone Oxidoreductase as a Site of Na+-Dependent Activation in the Respiratory Chain of Marine Vibrio alginolyticus (1979)

UNEMOTO, Tsutomu, HAYASHI, Maki

The site of Na+ activation in the respiratory chain of the marine bacterium, Vibrio alginolylicus, was investigated. The respiratory chain system contained ubiquinones (Q), menaquinones (MK),...

Kinetics of the Salt Modifications of Glucose 6-Phosphate Dehydrogenase Purified from a Marine Vibrio alginolyticus (1977)

UNEMOTO, Tsutomu, KANBAYASHI, Noriko, HAYASHI, Maki, HAYASHI, Makoto

Glucose 6-phosphate dehydrogenase was partially purified from a marine Vibrio alginolyticus. The enzyme specifically required NADP+ as a coenzyme and showed no significant activity toward...

Na+-Dependent Activation of NADH Oxidase in Membrane Fractions from Halophilic Vibrio alginolyticus and V. costicolus (1977)

UNEMOTO, Tsutomu, HAYASHI, Maki, HAYASHI, Makoto

Membrane-bound NADH oxidase activities from slightly halophilic marine Vibrio alginolyticus and moderately halophilic V. costicolus required 0.3 and 0.5 M Na+ respectively, for maximum activity;...

KtrAB, a New Type of Bacterial K+-Uptake System from Vibrio alginolyticus

Nakamura, Tatsunosuke, Yuda, Rieko, Unemoto, Tsutomu, Bakker, Evert P.

Vibrio alginolyticus contained two adjacent genes, ktrA and ktrB, which encode a new type of bacterial K+-uptake system. KtrA and KtrB are peripheral and integral membrane proteins, respectively. Six...
