Hello dingh09,
Yes, multiple molecules are common in a single PDB files.
For example, see the antibody structure 4NZU:
http://www.rcsb.org/pdb/files/4NZU.pdb
In that file, "CHAIN: L" is the light chain poly-peptide and the
"CHAIN: H" is the heavy chain poly-peptide.
Likewise, any co-crystal structure implies at least two molecules. The
are plenty of co-crystals at RCSB.
A solvated structure is yet another example of multiple molecules in a
single PDB file. Granted that water is a small molecule but it is
still a molecule. ;)
For more on the PDB standard, see
http://www.wwpdb.org/documentation/file-format-content/format33/sect2.html#HEADER
In particular, look for section COMPND and look at the first and
second examples.
I hope this helps.
Ivan
