previous studies done under map-depleted conditions ( sternlicht , h. , and ringel , i . ( 1979 ) j. biol . chem . 254 , 10540 ) suggested that tubulin binds to the ends of the microtubule with an apparent dissociation constant ( affinity t-1 ) which increases as the tc/tubulin ratio in the microtubule increases .
