    Notizen: Abstract Sucrose phosphate synthetase (EC 2.4.1.14) is the key enzyme for sucrose synthesis in Dunaliella tertiolecta. It has been partially purified and characterized. The enzyme contains one binding site for uridine diphosphoglucose and two binding sites for fructose-6-phosphate; it is allosterically controlled by fructose-6-phosphate. Inorganic phosphate stimulates the enzymic activity, particularly in the presence of higher concentrations of fructose-6-phosphate. Sucrose phosphate synthetase is not halophilic or halotolerant. The temperature dependence of the enzymic activity cannot fully explain the observed increase in sucrose synthesis in Dunaliella by elevated temperature.

    Notizen: Abstract The halotolerant phytoplankton alga Dunaliella tertiolecta was found to be able to synthesize considerable amounts of sucrose. Because this is in contradiction to the current literature, the physiologic conditions required for sucrose biosynthesis were investigated. Sucrose is only synthesized above a jump temperature, which depends on the NaCl concentration in the medium. Unlike earlier results, which showed that glycerol is synthesized only under photosynthetic conditions, sucrose is also produced in the dark, however at a reduced rate. In the dark, sucrose synthesis ceases after 24 h, thus indicating that sucrose is formed from storage substances.

    Notizen: Abstract The temperature dependence of membrane fluidity has been studied by means of spin labeling of intact Dunaliella cells, in the presence of different NaCl concentrations. The obtained data support the proposed hypothesis that the permeability of the chloroplast envelope to fructose-6-phosphate at higher temperatures in the basic regulatory mechanism for sucrose synthesis in Dunaliella.
