## Abstract Demembranated cilia of Tetrahymena pyriformis were extracted with KCl or TrisβEDTA and the crude dyneins from each resolved by sucrose density gradient sedimentation into 14SβK, 30SβK, 14SβE and 30SβE dyneins, respectively. The calmodulin activation ratio (ATPase activity in presence of
Cilia from the protozoan Tetrahymena pyriformis were demembranated and then extracted for 5 min with a buffer containing 0.5 M NaCl. The briefly extracted axonemal pellet was then reextracted for about 20 hr. The soluble material obtained from each extraction was resolved into 14S and 30S dynein ATP
