Before revision:  We focused on the relation between the intrinsic disorder of {\alpha}-syn and macromolecular crowding, and constructed a lattice gas model of {\alpha}-syn including crowding agents based on statistical mechanics.
After revision:  We focused on the relation between the intrinsic disorder of {\alpha}-syn and macromolecular crowding, and constructed a lattice gas model of {\alpha}-syn in contact with a crowding agent reservoir based on statistical mechanics.
