abstracts
Our cryo-EM structure of the actin-tropomyosin-myosin complex provides novel insights into the interaction between actin, myosin and tropomyosin. The pseudo-atomic model of the complex obtained from fitting crystal structures into the map defines the large actin-myosin-tropomyosin interface and the molecular interactions between the proteins in detail. It indicates that the N-terminus of actin is involved in this interaction. Our data suggest that tropomyosin is stabilized by electrostatic interactions with myosin and likely slides rather than rolls on F-actin when moving from the blocked to the myosin-bound state [1].
CRYO-EM
access
The cryo-EM structure of squid hemocyanin, obtained using a multi-symmetry refinement protocol in SPHIRE, reveals an unexpected breaking of fivefold symmetry in the central ring and a striking arrangement of the subunits.
CCP-EM
Two approaches for the selection of filaments from cryo-EM micrographs are described.
