[Structural and biochemical characteristics of Escherichia coli cells with various levels of secretable alkaline phosphatase].

Abstract

The biochemical and structural peculiarities of Escherichia coli cells with different rates of synthesis of secreted alkaline phosphatase were studied under the conditions of repression, derepression and constitutive synthesis. The enzyme synthesis was shown to correlate with the redistribution of free and membrane-bound ribosomes in the cells, with an increase in their proportion, and with a reconstruction of the cell ultrastructural organization.
