The synthesis and degradation of the soluble and sodium dodecyl sulfate-(SDS)-solubilized protein fractions of Escherichia coli were studied in both growing and nongrowing cultures. When separated according to molecular weight on SDS-polyacrylamide gels, the proteins of both fractions of growing cells undergo no measureable differential synthesis or degradation during logarithmic growth. However, when a leucine auxotroph is suspended in medium containing 5.3 muM leucine (a level that will not sustain growth), the SDS-solubilized protein of such a nongrowing culture shows a rapid synthesis of two protein components (32,000 and 12,000 daltons) found only in the out membrane. |
