Abstract
IN a recent communication1 it was reported that the ribbon-shaped filaments of paramyosin, isolated from the smooth-muscle fibres of molluscs, closely resemble in their submicroscopic structure the ‘crystals’ of a tropomyosin which is present in these muscles in very large amounts2–4. This implies that paramyosin ribbons contain tropomyosin, that their fine structure is due to their content of this protein, and that ‘paramyosin’, which until now has been defined only in structural terms5,6, may in fact be identical with tropomyosin.
