Bacterial Microcompartment
Bacterial microcompartments are widespread bacterial organelles that are made of a protein shell that surrounds and encloses various enzymes. These compartments are typically about 100-200 nanometres across and made of interlocking proteins. They do not contain lipids since they are not surrounded by a membrane. Protein-enclosed compartments are also found in eukaryotes, such as the mysterious vault complex.
