Extended Data Fig. 4: TEM analyses revealed the formation of silk-based compartments in the cytoplasm.
From: Formation and functionalization of membraneless compartments in Escherichia coli
a, TEM image of fixed control cells without silk I16 expression. TEM images of microtome slices of E. coli cells without (b) and with expression of silk I16 protein (c). The cell samples were taken at 6 h after exposure to the inducer IPTG for silk gene expression at 37 °C. Note that clear compartmentalization was observed in the silk-expressing cells, but not in the control, non-expressing cells. Data in a–c are representative of n = 3 independent experiments.
