Electromagnetic and Informational Process in Biomolecular Polymers

[an error occurred while processing this directive] It has been suggested that proteins with appropriate electrical and structural characteristics are suitable building block candidates of biological or quantum computers due to their small size, minute energy requirements and tendency to self-organize into ordered tubes and networks. We developed theoretical predictions concerning the properties of the cytoskeletal protein tubulin, its aggregates (microtubules-MTs), and associated proteins (MAPs), pertaining to their possible role in storing and processing information in biomolecular circuits. Simulations based on the tubulin atomic structure and amino acid sequence suggest this molecule has a permanent electric dipole moment, which changes magnitude and direction, as tubulin undergoes a conformational change. This property may be used as the basis for an electronic binary switch.

Theoretically our biophysical analysis has yielded predictions that under certain circumstances, MTs can be modeled as isolated quantum-electrodynamic (QED) cavities and dipole-moment "flip-waves" can propagate along MTs conceivably carrying intracellular information. Teleportation (transfer of information without any transfer of matter or energy) is also a direct consequence of this model.

Experimentally we are measuring the dielectric properties of tubulin at various frequencies to determine the electric dipole moment. Although crucial to these theories and to a better understanding of MT structure, function, polymerization, energy transduction and drug interaction, so far, the electric dipole moment of tubulin has never been experimentally determined and flip waves have not been directly observed. To this end, we are using Surface-Plasmon-Resonance (SPR)-based experiments to measure the dielectric constant of tubulin at various frequencies and relate it to its electric dipole moment and prepares the way to detect flip waves. By implementing a femtosecond laser pulse correlation technique we plan to be able to also detect the conjectured quantum bit (qubit) nature of tubulin dimers checking for quantum coherence and entanglement among the dipole moments of micrometer-separated tubulin dimers.
