A New Protein Lattice Model

Abstract

Abstract: Anew protein lattice model basing on the bond fluctuation model is performed in this paper. Through investigation of two-dimensional protein structure using our lattice model, we find that our two-dimensional protein chains have more contacts. The conformations Ω₀ may be expressed as Ω₀=γ^N, here Nis chain length and γ =4768, and the average compactness < ρ(N) > is close to 0.31-0.32. For the given HPsequences, our protein lattices have lower ground state energies. Comparisons with two-dimensional square lattice model are also made.

Key words: Protein, Bond fluctuation model, Conformation, Contact
