The 33kDa fragment (PDB:1H6W)  was generated in the presence of EDTA <ref name=r3>PMID: 12888344</ref>. This fragment contains the residues <scene name='Sandbox_Reserved_717/Myfirstscene/1'>85-395</scene> and <scene name='Sandbox_Reserved_717/Mysecondscene/1'>518-527</scene> .  The residues 397-517 are lacking because of internal deletion.

The 33kDa fragment can be further sub-divided into two subunits <ref name=r3>PMID: 12888344</ref>. The <scene name='Sandbox_Reserved_717/Mythirdscene/1'>neck</scene>  (residue 333-341) and the collar (residues <scene name='Sandbox_Reserved_717/Mythirdscene/2'>342-396 </scene> plus <scene name='Sandbox_Reserved_717/Mythirdscene/3'> 518-527</scene>). The neck connects the body of the fibre to its C-terminal collar and receptor-binding site. It consists of a triple alpha-helix which is built by the residues 333-341.

The neck connects the body of the fibre to its C-terminal collar and receptor-binding site. It consists of a triple alpha-helix which is built by the residues 333-341.
The collar domain is a small globular domain. It contains six beta-strands and an alpha-helix <ref name=r3>PMID: 12888344</ref>.

For generating the 45kDa fragment the full length gp12 was co-expressed with its chaperone gp57 and purified <ref name=r3>PMID: 12888344</ref>. Like the 33kDa fragment it also starts with the amino acid Leu85. The 45kDa fragment contains the residues <scene name='Sandbox_Reserved_717/Mythirdscene/4'>397-517</scene> , which are in the 33kDa fragment internal deleted <ref name=r3>PMID: 12888344</ref> .

Like the 33kDa fragment the 45kDa fragment can also be divided into two subunits. These two subunits are called head (residues <scene name='Sandbox_Reserved_717/Mythirdscene/5'>397-446 </scene> and residues <scene name='Sandbox_Reserved_717/Mythirdscene/6'>487-517</scene> ) and <scene name='Sandbox_Reserved_717/Mythirdscene/7'>bonnet</scene>  (residues 447-487). On the border between the head and the bonnet subunit there is a metal-binding site <ref name=r3>PMID: 12888344</ref>.
