HELP! LOOKING FOR YEAST KEX2 PROTEASE

[zong]

Hi there, 
 
   Does anybody know where I can find the yeast endoprotease KEX2 or the   
pro-protein convertases (PCs)? After comparing our protein sequence date   
and the sequence from the cDNA, we find our protein has been processed at   
its C-terminal and the processing site is at the double basic amino   
acids. We are interested in using the KEX2 to treat the inactive   
pro-protein and wish we can activate this pro-protein in vitro. 
 
You can reach me at (217) 333-9683 or email me at zong at uxa.cso.uiuc.edu. 
 
Thank you very much.
