   Importantly you also need the protease cleavages to loosen up the structure disassociate the trimer so that the 6helix bundle can form and the fusion peptide (S) can interact with the cell membrane. REcall that in addition to the FCS there is also the S2' site with a putative fusion peptide right next door. So I don't see why ther couldn't beanother cleavage before the FCS with a fusion peptide here as well.

   So need to show that the elastase cleavage site is used but it's not out of the question and could make some sense. THere is a fusion peptide for sure between the FCS and S2' -looks like there may be one before the FCS as well.

   I still think that the most likely thing that Doug and the Q613H/R mutants are doing is adjusting the charge there andloosening up the trimer, but no reason that they couldn't be generating a new or better cleavage site as well.

   @Robert Garry Speaking of Cara's picture - She and Jonny both have them removed from the website - Jonny also scrubbed his weed research...

   @Robert Garry Do you think Jonny is actually involved?

   @Robert Garry So could have all been harvested off the web, I guess.
