Mv. Sataric et al., KINK-LIKE EXCITATIONS AS AN ENERGY-TRANSFER MECHANISM IN MICROTUBULES, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 48(1), 1993, pp. 589-597
A model is presented that is intended to provide a realistic physical
picture of the energy-transfer mechanism in cell microtubules. A class
ical phi4 model in the presence of a constant electric field is used a
s a conceptual basis. It is demonstrated that kinklike excitations ari
se as a result of the guanosine 5'-triphosphate (GTP) hydrolysis and t
hat an intrinsic electrical force may cause them to propagate along a
microtubule. A discussion is given on the possible effects of these ex
citations on the dynamics of microtubules.
