This was my approach to designing the protease sites -Phillip
 
 
Using the DSSP algorithm from PDB, the parts of the protein with no alpha helices, beta sheets, or turns and five or greater amino acids are the following. 
 
30-35, 64-72, 123-129, 131-139, 216-220, 228-233, 298-302, 331-336, 417-422
 
Revised sites in terms of location. Bold indicates insertion
 
 
Top candidates are based on two criteria:
 
1. Exposure at the surface for protease accessibility
 
2. Speculated to have minimal conformational changes by insertion
 
In general, original proline residues on the side were kept, in case they were involved in transitioning between secondary structural elements.  Also, insertions were flanked  with glycines in order to allow extra flexibility. 
 
 
131-139*:  (KTDDNPDGA) to KTDDNPD'''GLVPRGS'''GA.  Satisfies 1 and 2.
 
 
228-233:  (DRTLPI) to DRTL'''GLVPRGSG'''IPI.  Satisfies 1.
 
 
331-336*:  (TRPILS) to TRP'''GLVPRGSG'''ILS.  Satisfies 1 and 2, depending on oligomerization geometry.
 
 
298-302*:  (IPSGP) to IPS'''GLVPRGSG'''P.  Satisfies 1 and 2, depending on oligomerization geometry.
 
 
216-220:  (IDVPA) to IDV'''GLVPRGSG'''PA. 
 
 
64-72:  (SSQPTTGYD) to SSQPTT'''GLVPRGSG'''YD
 
 
417-422:  (RMGAVT) to RMG'''LVPRGSG'''AVT.  Satisfies 1, depending on geometry.
