However, when these protofilaments are part of a polymerized microtubule, the stabilizing interactions created by the surrounding lattice lock subunits into a straight conformation, even after GTP hydrolysis.
Porén, cando estes protofilamentos forman parte dun microtúbulo polimerizado, as interaccións estabilizantes creadas polo tramado que a rodea fixan as subunidades na conformación recta, mesmo despois da hidrólise GTP.
