Structures of large nucleoprotein complexes

[Victor Jongeneel]

Hi Netters!

I am trying to put together (for teaching purposes) a collection of images of 
nucleic acids and nucleoproteins, ending up with large complexes such as 
ribosomes and nucleosomes.  I know that the 3D shapes of these complexes are 
known, but haven't found anything in any of the structural databases (after a 
fair bit of nosing around the Web).

Does anyone know where, if anywhere, structures of ribosomes and/or 
nucleosomes may be deposited?  I can handle many different file formats for 
display (contour maps, polygon meshes, coordinates etc.)

Thanks for any info!
