Chains	Enzyme Name	Description	Catalytic Residues
A	diphosphate---fructose-6-phosphate 1-phosphotransferase M-CSA #653	The Lyme disease causing Spirochete Borrelia burgdorferi uses pyrophosphate (PPi) rather than ATP as the source of phosphate for the phosphorylation of Fructose-6-phosphate to Fructose-1,6-bisphosphate in glycolysis. This strategy, common to many anaerobic bacteria, allows ATP to be conserved for other processes such as maintaining a proton gradient. The enzyme catalysing this process shares around 23% sequence identity to the E. coli PFK and many structural features differ between the two enzymes. However, the active sites do share a similar structure with conservation of key residues, so the mechanism of the reaction is almost certainly the same for each.
