title: In situ stability of uridylyl removing-uridylyltransferase of Escherichia coli.
abstract: The difference in sensitivity of UR/UT toward Lubrol WX permeabilization treatment of stationary phase E. coli cells is not uniquely related to nitrogen availability during cellular growth. The sensitivity of UR/UT to detergent treatment appears to be related to differences in the balance between fermentative and oxidative glucose metabolism. The possible occurrence of a third cycle in the glutamine synthetase regulatory cascade mechanism is considered.
