When exposed to that environment, the cells activated a stress response that changed the clumping proteins back to the no-clumping shape.
The resulting cap in this in vitro reconsti-. tuted structure is very similar to the capped minus ends of. microtubules that have been observed in yeast cells (figure 1 c, right) [15], and at the A-tubule of the centriole [9].
