One way is you can wrap a union around your include file as follows:

#declare Protein_1 = union {   #include "Bunch_O_Triangles.inc"  }
object{Protein_1  rotate <?,?,?> translate <?,?,?>  }

You might consider using your editor to do a search and replace-all for all
those texture statements, if they're all the same, and replace them with
nothing or a whitespace character... and then just apply one copy of the
texture to the union or the object.
