Immunological similarities between specific chloroplast ribosomal proteins from Chlamydomonas reinhardtii and ribosomal proteins from Escherichia coli.
Polyclonal antibodies were elicited against seven of the 33 different proteins of the large subunit of the chloroplast ribosome from Chlamydomonas reinhardtii. Three of these proteins are synthesized in the chloroplast and four are made in the cytoplasm and imported. In western blots, six of the seven antisera are monospecific for their respective large subunit ribosomal proteins, and none of t...
متن کاملThe Double Life of Ribosomal Proteins
Many integral proteins of the ribosome also carry out extra-ribosomal functions as independent polypeptides, raising questions as to their evolutionary derivation. In this issue of Cell, Mazumder et al. report a surprising new twist in the dual life of these molecules: as part of a cellular response to interferon, a large-subunit protein dramatically exits the ribosome to bind and inhibit the t...
متن کاملRibosomal proteins. XII. Number of proteins in small and large ribosomal subunits of Escherichia coli as determined by two-dimensional gel electrophoresis.
Two-dimensional gel electrophoresis separates all of the component proteins of the ribosomal subunits of Escherichia coli. This method shows 21 proteins in the 30S, and 34 proteins in the 50S, subunit.
متن کاملRibosomal proteins: functions beyond the ribosome.
Although ribosomal proteins are known for playing an essential role in ribosome assembly and protein translation, their ribosome-independent functions have also been greatly appreciated. Over the past decade, more than a dozen of ribosomal proteins have been found to activate the tumor suppressor p53 pathway in response to ribosomal stress. In addition, these ribosomal proteins are involved in ...
متن کاملAncestral Interactions of Ribosomal RNA and Ribosomal Proteins.
We have proposed that the ancient ribosome increased in size during early evolution by addition of small folding-competent RNAs. In this Accretion Model, small RNAs and peptides were subsumed onto subunit surfaces, gradually encasing and freezing previously acquired components. The model predicts that appropriate rRNA fragments have inherited local autonomy of folding and local autonomy of asse...
