Encapsulins: Structure, Properties, and Biotechnological Applications
Biochemistry. Biokhimiia(2023)
Abstract
In 1994 a new class of prokaryotic compartments was discovered, collectively called “encapsulins” or “nanocompartments”. Encapsulin shell protomer proteins self-assemble to form icosahedral structures of various diameters (24-42 nm). Inside of nanocompartments shells, one or several cargo proteins, diverse in their functions, can be encapsulated. In addition, non-native cargo proteins can be loaded into nanocompartments, and shell surfaces can be modified via various compounds, which makes it possible to create targeted drug delivery systems, labels for optical and MRI imaging, and to use encapsulins as bioreactors. This review describes a number of strategies of encapsulins application in various fields of science, including biomedicine and nanobiotechnologies.
