title: [Changes in the pool of polyamines [correction of polyvitamins] during transition from anaerobic to aerobic conditions and localization of enzymes for their synthesis in Escherichia coli cells].
abstract: The content of intra- and extracellular polyamines and the activity of enzymes mediating their synthesis change depending on the regime of cell aeration. The pool of putrescine rises abruptly upon the transition from anaerobic to aerobic conditions owing to its liberation from the bound state as well as due to an increase in the activity of ornithine decarboxylase; as a result, the structural-functional organisation of membranes is restored. The free pool of cadaverine appears because, presumably, its binding to membranes is upset and the activity of lysine decarboxylase rises. The localisation of the enzymes for polyamine synthesis in the cell seems to be determined by the specific action of their products on particular cellular structures and metabolic processes in Escherichia coli cells.
