Abstract: S1.00077 : Clay platelets in a matrix of amino acids (of a clay binding peptide M1) homopolymer: binding, unbinding, dispersion, and self-assembly by a coarse-grained Monte Carlo simulation
Author:
Monte Carlo simulations are performed to study binding and
distribution of a
stack of clay platelets in a matrix of homo-polymers of residues.
The set of
residue monomers is selected from a clay binding peptide
($M1)^{1}$. The length
of homopolymer is same as that the peptide $M1$. Clay platelet
and amino acid
polymer (AAP) are described by a bond-fluctuation model$^{2}$ where
specificity of each residue interaction is incorporated. Each
node (of clay
platelets and AAP) performs their stochastic motion via
Metropolis algorithm
subject to steric and excluded volume constraints. We examine the
mobility
of AAP and platelets and their density profiles. We find that
dispersion and
binding of each AAP is unique and differ from that of the clay
platelets in
peptide $M1$ matrix.
