RMSF of simulated WT structure (red) and mutant G56S structure (black); B factors (C^α atoms) of the WT X-Ray crystal structure (green).

<p>Note that the residue numbers in D chain, which includes 381 amino acids as C chain, were counted from No. 382 to No. 762. The mutation site G56S in both C chain and D chain is pointed to by the blue arrow.
