30-S核糖体亚基经热变性的16-S rRNA重组后,在体外可参与溶菌酶的合成。因此,16-S rRNA对重建过程贡献的所有信息都携带在该RNA的一级序列中。由30-S亚基蛋白和热变性的16-S rRNA重构的30-S亚基的特异性蛋白合成活性约为使用未加热的16-S rRNA时观察到的活性的三分之一,并且与在0.1 mM Mg 2+存在下解离70-S核糖体后分离的30-S颗粒的活性相当。
30-S ribosomal subunits which have been reconstituted using heat-denatured 16-S rRNA can participate in the synthesis of lysosyme in vitro. Therefore all the information contributed by 16-S rRNA to the reconstitution process is carried in the primary sequence of this RNA. The specific protein-synthesizing activity of 30-S subunits reconstituted from 30-S subunit proteins and heat-denatured 16-S rRNA is about one third of that observed if unheated 16-S rRNA is used and is comparable to the activity of 30-S particles isolated after dissociation of 70-S ribosomes in the presence of 0.1 mM Mg2+.
