Isolation of Aulacomya paramyosin.
Tropomyosin A or paramyosin has been isolated from the adductor muscle of Aulacomya magellanica. It has in common with other tropomyosins A the method used for extracting it from adductor muscle, its solubility, facility of crystallization, ammonium sulphate range of precipitation, amino acid composition and behaviour when digested with trypsin. As a particular feature it exhibits an unusual low viscosity for this type of tropomyosin. Its molecular weight, determined by the Archibald approach-to-sedimentation-equilibrium method, is 258000+/-16000.
