Gene

PFK

Organism
Calanus finmarchicus (Calanus tonsus)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.By similarity

Catalytic activityi

ATP + D-fructose 6-phosphate = ADP + D-fructose 1,6-bisphosphate.

Cofactori

Mg2+By similarity

Enzyme regulationi

Allosterically activated by ADP, AMP, or fructose 2,6-bisphosphate, and allosterically inhibited by ATP or citrate.By similarity
