WebThe spatial separation depends on the presence of ER-targeting signal sequence on the protein being synthesized, thus, a particular ribosome might be ER-bound while synthesizing one protein and free in the cytosol when translating another protein. So, the correct answer is ' On ribosomes present in cytoplasm as well as in mitochondria'. WebOur findings suggest that stable S-nitrosylation reflects a protein conformation change that shields the nitrosothiol. To identify stable protein nitrosothiols, we developed a proteomic method for profiling S-nitrosylation. We examined the stability of over 100 S-nitrosylated proteins, and identified 10 stable nitrosothiols.

WebAfter translation, proteins within the ER make sure that the protein is folded correctly. If after a first attempt the folding is unsuccessful, a second folding is attempted. If this fails too the protein is exported to the cytosol and labelled for destruction. Aside from the folding, there is also a sugar chain added to the protein.
