WebBinding of c-di-GMP by DgrA leads to destabilization of the flagellar motor protein FliL. Though the mechanism of action is not known, it does not act at the level of fliL transcription, suggesting that DgrA-mediated motility disruption functions on already-formed flagella. The PleD paralog PopA transduces c-di-GMP signaling by a different ... WebA slime layer is loosely associated with the bacterium and can be easily washed off, whereas a capsule is attached tightly to the bacterium and has definite boundaries. Capsules can be seen under a light microscope by placing the cells in a suspension of India ink. The capsules exclude the ink and appear as clear halos surrounding the bacterial ...
