<b>Bacterial membrane coat proteins?</b>

Members of the Planctomycetes-Verrucomicrobiaea-Chlamydiae superphylum of bacteria have a compartmentalized cellular organization. Santarella-Mellwig et al. (e1000281) show that members of this superphylum have proteins whose domain architecture is similar to that of eukaryotic membrane coat proteins, which have not previously been detected in prokaryotes. These proteins localize partly at the membrane of vesicles formed inside bacterial cells. Illustrated is a cell of Gemmata obscuriglobus, a member of the Planctomycetes phylum. DNA is colored purple and the vesicle-containing compartment green.
