title: Balanced production of 30S and 50S ribosomal proteins after a nutritional shift-up.
abstract: The synthesis of bulk ribosomal protein (r-protein) after a nutritional shift-up in Escherichia coli B/r was examined. It was found that the molar ratio of the net synthesis rates of 30S and 50S r-protein remains constant during the transition period after the shift-up and equal to the preshift ratio. The implications for the control of ribosome synthesis are discussed.
