Recall that S855 and S858 in RPTOR are represented, for simplicity, as a single component named S855_S859, which is allowed to be unphosphorylated (0), singly phosphorylated (P), or doubly phosphorylated (PP). (See the molecule type definition for RPTOR.) The rate constant in the rule of Equation (8B) is specified as twice that for the rule of Equation (8C) because the 0 to P state transition for site S855_S859 (i.e., the transition from an unphosphorylated state to a singly phosphorylated state) is expected to occur twice as fast as the P to PP transition (i.e., the transition from a singly to doubly phosphorylated state).
