1-phosphofructokinase
In enzymology, 1-phosphofructokinase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are ATP and D-fructose 1-phosphate, whereas its two products are ADP and D-fructose 1,6-bisphosphate. The enzyme was first described and characterized in the 1960s.
This enzyme belongs to the phosphofructokinase B or Ribokinase family of sugar kinases, specifically those transferring phosphorus-containing groups with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:D-fructose-phosphate 6-phosphotransferase. Other names in common use include fructose-1-phosphate kinase, 1-phosphofructokinase , D-fructose-1-phosphate kinase, fructose 1-phosphate kinase, and 1-phosphofructokinase. This enzyme participates in fructose and mannose metabolism. The members of the PfkB/RK family are identified by the presence of three conserved sequence motifs and their enzymatic activity generally shows a dependence on the presence of pentavalent ions.
