    The structure of the 60 kDa pyrophosphate (PP(i))-dependent phosphofructokinase (PFK) from Borrelia burgdorferi has been solved and refined (R(free) = 0.243) at 2.55 A resolution. The domain structure of eubacterial ATP-dependent PFKs is conserved in B. burgdorferi PFK, and there are three large insertions relative to E. coli PFK, including a helical domain containing a hairpin structure that interacts with the active site. Asp177, conserved in all PP(i) PFKs, negates the binding of the alpha-phosphate group of ATP and likely contacts the essential Mg(2+) cation via a water molecule. Asn181 blocks the binding of the adenine moiety of ATP. Lys203 hydrogen bonds to a sulfate anion that likely mimics PP(i) substrate binding.
