Fig. 4: Cryo-ETs of HF-treated S. coelicolor WT sacculi show double layers of PG.
From: Teichoic acids anchor distinct cell wall lamellae in an apically growing bacterium
The micrographs in a and b are the same sacculus, displayed at different Z heights, the blue arrows highlight the presence of a double layer. The micrographs at c show a collapsed double layer at the apex, highlighted by the red arrow. The double layer of the sacculus in c can also be seen in a ZX plane (d) at the approximate Y height depicted in c by the dashed line. Scale bars 100 nm .
