:Is anyone aware of an affinity technique (or the like) that will
:selectively purify fatty acid modified proteins (specifically
:palmitoylated ones?).
:
Those that *are* palmitoylated or those that *can* (and maybe are
to begin with)? If former, I doubt any selective technique exists -
palmitate is simple moiety and HIC would pick up too many
simply hydrophobic proteins as a huge background. If latter, then
in case of periferal membrane proteins that are bound by virtue
of palmitate, treatment of well-washed memebranes with
hydroxylamine will release them into solution.
