Glucose dehydrogenase of Chlorogloeopsis fritschii.
Blue-green bacteria metabolize carbohydrates via the oxidative pentose phosphate cycle (Wildon & ap Rees, 1965; Cheung & Gibbs, 1966; Pearce & Carr, 1969; Pelroy et al., 1972). Glucose enters this pathway through the reactions catalysed by hexokinase and glucose 6-phosphate dehydrogenase; both of these enzyme have been detected in obligately phototrophic and facultatively heterotrophic species ...
متن کاملThe Presence of Malate Dehydrogenase in Thylakoids of Anabaena cylindrical Nostoc muscorum and Chlorogloeopsis fritschii
The location o f malate dehydrogenase in the cyanobacteria, Anabaena cylindrica, Nostoc muscorum and Chlorogloeopsis fritsch ii was investigated by the fractionation o f cell-free ex tracts. The bulk o f the enzyme activity was associated with the thylakoid membrane fraction, which also exhibited complete photosynthetic electron transport reactions. Malate dehydro genase activity and photosys...
متن کاملHepatic Glutamate Dehydrogenase Activity and the Presence of Ammonia and Urea in the Circulatory Fluid of Channa Gachua in Water-Restricted Condition
Ammonia is the chief excretory product in fishes. However, non-availability of enough of water in the habitat, may lead to the formation of urea, in fishes. In the present study, the possible role of urea formation to avoid the toxicity of ammonia under water-restricted condition was tested in Channa gachua. Circulatory urea and ammonia were estimated in the blood of the fishes and glu...
