I have found the people at the pdb very helpfull and accomodating. I think the key point is to /discuss/ the issue with them instead of 'demanding' a certain way of deposition. The depositors may have their reasons for certain namings, but the pdb has its reasons too, often based on a much broader aplicability than the single user. I'm sure when the problem and reasons are stated, a compromise can be found. In this case I see no problem whatsoever naming the parts with different chain names, whereas I see a problem deositing one chain with partly iverlapping sequence numbers. Also the referencing of the sequnece database entries gets simpler.
