Protein

ATP-dependent 6-phosphofructokinase subunit alpha

Gene

PFK1

Organism
Komagataella pastoris (strain GS115 / ATCC 20864) (Yeast) (Pichia pastoris)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein 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). Involved in the modulation of glucose-induced microautophagy of peroxisomes independent of its ability to metabolize glucose intermediates.1 PublicationUniRule annotation

Catalytic activityi

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

Cofactori

Magnesium.UniRule annotation

Enzyme regulationi

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