FUNCTIONCatalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.
CATALYTIC ACTIVITY Reaction=ATP + beta-D-fructose 6-phosphate = ADP + beta-D-fructose 1,6- bisphosphate + H(+); Xref=Rhea:RHEA:16109, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:32966, ChEBI:CHEBI:57634, ChEBI:CHEBI:456216; EC=2.7.1.11;
COFACTOR Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
PATHWAYCarbohydrate degradation; glycolysis; D-glyceraldehyde 3- phosphate and glycerone phosphate from D-glucose: step 3/4.
SUBUNITHomodimer.
SUBCELLULAR LOCATIONCytoplasm.
SIMILARITYBelongs to the phosphofructokinase type A (PFKA) family. PPi-dependent PFK group II subfamily. Atypical ATP-dependent clade 'X' sub-subfamily.
