Using a variety of immunological techniques, the supernatant levels of ribosomal proteins were measured in mutants lacking the ribosomal proteins L1 or L11, and in wild-type strains. There was a 2.5--5-fold elevation of protein L11 level in the supernatant of strains lacking protein L1, compared to wild-type. In contrast, there was no elevation, but rather a diminution, in the corresponding L1 level in strains lacking protein L11, compared to wild-type. These results are consistent with a model for the control of expression of the L11-L1 operon in which protein L1 is an inhibitor of expression of that operon, but protein L11 is not. The supernatant concentrations of other proteins were indistinguishable in all strains.
运用多种免疫学技术，对缺乏核糖体蛋白L1或L11的突变体以及野生型菌株的核糖体蛋白上清液水平进行了测量。与野生型相比，缺乏蛋白L1的菌株上清液中蛋白L11水平升高了2.5至5倍。相反，与野生型相比，缺乏蛋白L11的菌株中相应的L1水平没有升高，反而降低了。这些结果与L11-L1操纵子表达调控模型一致，在该模型中，蛋白L1是该操纵子表达的抑制剂，但蛋白L11不是。所有菌株中其他蛋白的上清液浓度没有差异。
