Each α or β monomer has a binding site for one molecule of GTP, the GTP that is bound to α and β-tubulin.

a) α-tubulin is physically trapped at the dimer interface and is never hydrolyzed

b) α-subunit is at the surface of the dimer and GTP bound by the α-subunit can be hydrolyzed

c) β-tubulin is physically trapped at the dimer interface and it can be hydrolyzed

d) β-subunit is at the surface of the dimer and GTP bound by the β-subunit can be hydrolyzed

Select the correct combination of α and β-tubulin?
