GroEL with some evidence of helices with handedness. A) The GroEL map with the highest level of detail displayed at a high contour level. Grooves that are typical of a right-handed α-helix can be seen in the tubes of EM density (grey). B) A fit of a GroEL crystal structure (colored ribbons) to the EM density shows the correspondence of the helices in the crystal structure to the helical tubes seen in the EM density map.
