The enzyme from rabbit muscle displays absolute stereoselectivity for the beta-anomer of D-fructofuranose 6-phosphate [9-11]. D-Tagatose 6-phosphate and sedoheptulose 7-phosphate can act as acceptors. UTP, CTP and ITP can act as donors. Not identical with EC 2.7.1.105 6-phosphofructo-2-kinase.

malfunction
a knockout of 6-phosphofructokinase I and blocking of the Entner-Doudoroff pathway efficiently increased riboflavin production in Escherichia coli
metabolism
in Escherichia coli, the phosphorylation of fructose-6-phosphate is catalyzed by two isozymes, 6-phosphofructokinase I (pfkA) and 6-phosphofructokinase II (pfkB). More than 90% of the phosphofructokinase activity relies on pfkA. A knockout of 6-phosphofructokinase I and blocking of the Entner-Doudoroff pathway efficiently increased riboflavin production in Escherichia coli
