we have extended our previous theoretical analysis of the kinetics for radioactive gtp incorporation into steady-state microtubules [ zeeberg , b. , reid , r. , & caplow , m. ( 1980 ) j. biol . chem . 255 , 9891-9899 ] to include the effects of a kinetic barrier for equilibration of labeled gtp with the tubulin e site .
