Abstract
X-ray diffraction shows that some degree of three-dimensional organization of actin exists in a molluscan smooth muscle. From X-ray patterns from this muscle and the toad sartorius, both in the living relaxed state, it can be deduced that the actin structure repeats at intervals of about 360 Å. In this respect the structure of actin may be similar in all muscles.
