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?
