P.27 right column top paragraph: "In addition to the eukaryotic PMLOs [proteinaceous membrane-less organelles] described in this article, membrane-less organelles known as inclusion bodies (IBs) can be found in some prokaryotic cells, especially in bacteria producing heterologous proteins [primary source]. These bacterial IBs contain aggregated proteins and, therefore, are similar to the eukaryotic aggresomes. In fact, both IBs and aggresomes represent a result of the regulated aggregation that originates from the altered proteostasis caused by the distortion in the cellular protein quality control system that includes chaperones and proteases [primary source]. In bacteria, IBs are found in the cytoplasm as dense spherical or cylindrical particles whose size is ranging from 0.2 to 1.2 μm and whose major constituent (80–95%) is the heterologously expressed protein. However, similar to other PMLOs, IBs may also contain other proteins and nucleic acids [primary source]." Primary source abstract: "The formation of inclusion bodies (IBs) constitute a frequent event during the production of heterologous proteins in bacterial hosts." |
