Fig. 1From: Cellular origin of the viral capsid-like bacterial microcompartmentsStructural comparison of the major shell protein (BMC-H) of bacterial microcompartments with the PII signaling proteins. a. Hexameric assembly of the BMC-H from Synechocystis sp. PCC 6803. b. BMC-H proteins from carboxysome, Pdu, and Eut microcompartments. c. PII signaling proteins from bacteria (Herbaspirillum and Mycobacterium), archaea (Methanocaldococcus) and plants (Arabidopsis). All structures are colored using the rainbow scheme from blue (N-terminus) to red (C-terminus) and indicated with the corresponding PDB identifiersBack to article page
