ProtSeq acid/base labile bonds

Hi, all,

I received nary a response to my question about cleavage of an expressed
protein at an FS bond--my understanding (and I don't have a reference for
this) is that FS is sensitive to (either) acid or base. I would like to
understand the chemical mechanism--and maybe we'll be able to avoid losing
the protein product. Does anyone have a reference?

Other acid labile bonds are DP, DG, GP and base labile bonds, TP, RP,
and NG. I have ST and FS on my list set aside--are they sensitive to
either base or acid?

Thanks for any help,
Deb
