Question

Some photosynthetic organisms perform phototaxis. Martian microbe 2 actually performs “scotophobia,” which is really an avoidance of the dark, rather than attraction to the light. This organism has a photoreceptor, and a two-component system similar to the CheA/CheY system of E. coli. Finally, it has a polar bundle of flagella, which operate in a similar way to E. coli: spinning counter clockwise, the flagella form a bundle and allow the cell to swim (i.e. a run). If the spin switches to clockwise, the bundle flies apart and the cell tumbles. The photoreceptor protein does not get methylated/demethylated as do the MCPs of E. coli, and as such is a more simple system.

The cells are bent in shape; antibodies to what protein might you target to identify the cause of this bend?

Explanation / Answer

The sape of a cell is due to the virtue of its cell wall. Hence antibody staining against cell wall components for eg. peptidoglycan might help you to determine the underlying cause of the bend
