highly selective inhibition of the production of some enzymes and toxins by certain antibiotics may be explained by the fact that the ribosomes synthesizing these proteins are peripherally localized and may be more sensitive to inhibition by low concentrations of antibiotics than are cytoplasmic ribosomes , although conclusive evidence for the synthesis of bacterial enzymes and toxins on membrane-bound ribosomes is lacking .
