You have discovered a single cellular eukaryotic organism that has very little vesicle trafficking. You suspect that this may be due to the relatively few formed microtubules that are observed in this species. Upon close examination, you find the microtubules that are present are unusually stable. When looking at an amino acid comparison with human alpha and beta tubulin, you notice that the alpha tubulin is identical, but the beta tubulin is different in the region responsible for GTP hydrolysis. You isolated the heterodimer subunits from this new species and put them in a cell free system in a GTP bound form of the heterodimer along with centrosome nucleation sites. How would the dynamics be different from human heterodimer subunits in the same situation
