wrt EtOh pptn and AmOAc salting, 

Am ions severely inhibit polynucleotide kinase, 

are there any other salts which have similar effects
 on other commonly used enzymes? I include in this 
category salts which co ppt with the DNA and thence inhibit enzymes.

BTW, I only ever use NaAc for ppting DNA
