Abstract
The isotonic shortening of glycerol-extracted preparations of molluscan catch muscles is inhibited at pH's and ionic strengths at which extracted paramyosin crystallizes. The isometric tension development is hardly altered under the same conditions. Consequently, the "catch mechanism" is explained on the basis of the crystallization of paramyosin.Keywords
