Web9 TUBULIN POLYMERISATION. The polymerisation of α- and β-tubulins to microtubules is an important biochemical event, which is essential for cell division, mitosis and growth in various plants and animals including helminths (Chapter 2, sec. 5.2) and protozoans. WebMay 14, 2024 · The binding of GTP to the E-site promotes tubulin polymerization and microtubule nucleation, so these rates exhibit a proportional dependence on the concentration of available GTP (Carlier et al., 1987). Polymerization and nucleation rate also strongly depend on the concentration of tubulin (Olmsted et al., 1974; Walker et al., 1988). chinese in blythewood sc
