contains the following statement:

"Electron transfer reactions and proton-coupled electron transfer
 processes readily occur at cryogenic temperatures in protein
 crystals along with small-scale movements of ligands and side chains."

I was under the impression that when frozen to LN2 temperatures
all chemistry came ceased. Is this inaccurate?

Any feelings about what impact this might have on cryonic suspendees?
