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. | Defined by 6 residues: GLY:A-82ARG:A-146ASP:A-177LYS:A-203THR:A-204ASP:A-206 | EC: 2.7.1.90 (PDB Primary Data) |
