Have a look at the original .pdb file.  Search for MISSING entries, and you will 
see that 1BL8 has a substantial number of atoms missing from the structure.  One 
of these is Arg27, which, given the fact that the first 22 residues are missing, 
becomes Arg5.

The first step in any simulation is to understand the flaws in your initial 
model.  In 1BL8, you have to deal with a large amount of missing information. 
Before doing anything else, you have to model in the missing atoms using the 
appropriate modeling software.
