Bacterial microcompartment
organelle-like structure in bacteria with a protein shell containing enzymes
A bacterial microcompartment is a structure inside bacteria. They are made of a protein shell which surrounds and encloses various enzymes.[1] They are similar to eukaryotic cell organelles, but do not have plasma membranes. They do not contain lipids.[2]
These compartments are typically about 100-200 nanometres across and made of interlocking proteins.[3]
Protein-enclosed compartments are also found in eukaryotes, such as enzyme encapsulation.[4]
