Protein-protein interactions in the rigor actomyosin complex

摘要

Since it has not been possible to crystallize the actomyosin complex, the x-ray structures of the indi- vidual proteins together with data ob- tained by fiber diffraction and electron microscopy have been used to build de- tailed models of filamentous actin (f- actin) and the actomyosin rigor complex. In the f-actin model, a single monomer uses 10 surface loops and two -helices to make sometimes complicated interactions with its four neighbors.
