It is well known that Mg ions bind PPi moieties (pyrophosphates) during DNA amplification such as PCR, LAMP or RCA. I assume they should do the same during DNA replication in vivo, i.e. inside cells, can anybody confirm it here?

Now, there are commercially available enzymes, pyrophosphotases, which digest pyrophosphates, such as EIPP (from E.Coli).

So are there any pyrophosphates present in a procaryotic cell and what could be their role?
