Reversible inactivation of dehydrogenases.
1. The reversible dissociation of lactic and malic dehydrogenases has been studied in detail and compared with the dissociation properties of triosephosphate dehydrogenase, a-glycerophosphate dehydrogenase, and liver alcohol dehydrogenase. 2. Evidence is presented for the existence of an intermediate form of lactic dehydrogenase with catalytic properties altered during reactivation. 3. The tech...
متن کاملThe effect of reversible inactivation of raphe nuclus on learning and memory in rats
The role of raphe nucleus (R.N) and serotonin in some behaviors such as sleep, cognition, mood, and memory has previously been reported. The median raphe (MR) nucleus is a major serotonin-containing cell group within the brainstem and is one of the main sources of projections to the septum and hippocampus. The hippocampus is widely believed to be essential for context-conditioning learning. Mor...

متن کاملPhysical Aspects of Reversible Inactivation
Most early investigations of the chemistry of endotoxins were limited to gross analyses. I t soon became apparent that subtler means of degradation, such as enzymes, were necessary to determine structural configurations and intramolecular relationships within the endotoxin complex. Just such a subtle endotoxin-degrading system was suggested by the observation of Hegemann (1954) that human plasm...
متن کاملReversible Inactivation of Typhus Rickettsiae
Rickettsiae that have been frozen and thawed in isotonic salt solutions show greatly decreased toxicity for mice, hemolytic activity, respiration, and infectivity for eggs. All these properties can be partially restored by incubation of the rickettsiae in the presence of DPN and coenzyme A for 2 hours at 34 degrees C. The extent of both inactivation and of subsequent reactivation is markedly af...
