In the video shown below, made by Katy Poncin, bacteria are covalently labeled on their surface with Texas Red. When they grow, it is obvious that the new envelope is incorporated at a single pole. But how are envelope components specifically incorporated at this site? Caroline showed that LptC (in green in the image below) is located at the new pole and at the division site ("div"), providing a molecular mechanism to explain unipolar insertion of lipopolysaccharide. PdhS (shown in red) is marking the old pole ("old") of the bacteria.
