to account for the fact that the microtubule assembly and disassembly rates are nonlinearly dependent upon the tubulin subunit concentration and for the effects of gdp-containing tubulin subunits on the kinetic properties of microtubules , our scheme includes nonproductive as well as productive binding of gtp- and gdp-containing tubulin subunits .
