Abstract:
:In an Escherichia coli B strain missing ribosomal protein L1, the synthesis rate of L11 is 50% greater than that of other ribosomal proteins. This finding is in agreement with the previous conclusion that L1 regulates synthesis of itself and L11 and indicates that this regulation is important for maintaining the balanced synthesis of ribosomal proteins under physiological conditions.
