GTP is hydrolyzed to GDP in a time dependent fashion. 3. if the rate of GTP hydrolysis is greater than the rate of GTP addition, the GTP cap shrinks until all GTP is hydrolyzied to GDP and the microtubule breaks apart into dimers ... Webton in the neurons. Hollow cylindrical parts of this network are microtubules. Fig. 1 shows the structure of microtubules. The diameter of microtubule is 25 nanometers(nm). Along its longitude, the wall of the microtubule is made up of 13 protein bres or proto laments. These proto laments are called tubules which are consisted by dimers of ...
