Annotation	The electrodynamics of metals is well understood within the Drude conductivity model, properties of insulators and semiconductors are governed by a gap in the electronic states. But there is a great variety of disordered materials that do not fall in these categories and still respond to external field in an amazingly uniform manner. At radiofrequencies delocalized charges yield a frequency-independent conductivity whose magnitude exponentially decreases on cooling. With increasing frequency, dispersionless conductivity starts to reveal a power-law dependence caused by hopping charge carriers. At low temperatures, such Universal Dielectric Response can cross over to another universal regime with nearly constant loss. Here we study a broad-band dielectric response of Shewanella oneidensis MR-1 extracellular matrix, cytochrome C and serum albumin. Applying concepts of condensed matter physics, we identify transport mechanisms to provide a deeper insight into the protein dynamics.
