Query: A Monte Carlo simulation of a protein (CoVE) in a matrix of random
  barriers   Monte Carlo simulations are performed to study structure and dynamics of a
protein CoVE in random media generated by a random distribution of barriers at
concentration c with a coarse-grained model in its native (low temperature) and
denatured (high temperature) phase. The stochastic dynamics of the protein is
diffusive in denature phase at low c, it slows down on increasing c and stops
moving beyond a threshold (cth = 0.10). In native phase, the protein moves
extremely slow at low c but speeds up on further increasing c in a
characteristic range (c = 0.10 - 0.20) before getting trapped at high c (cth =
0.30). The radius of gyration (Rg) of CoVE shows different non-monotonic
dependence on c (increase followed by decay) in native and denature phase with
a higher and sharper rate of change in farmer. Effective dimension (D) of CoVE
is estimated from the scaling of structure factor: in denatured phase, D = 2 (a
random coil conformation) at low c (= 0.01 - 0.10) with appearance of some
globularization i.e. D ? 2.3, 2.5 at higher c (= 0.2, 0.3). Increasing c seems
to reduce the globularity (D = 3) of CoVE in native phase.
