In addition to increasing gluconeogenesis, glucagon inhibits glycolysis. Phosphofructokinase-1 (PFK-1) phosphorylates the C-1 position of F-6-P, converting F-6-P into F(1,6)P2, an early and rate-limiting step in glycolysis. Similar to FBPase-1, PFK-1 is also allosterically regulated by F(2,6)P2 but in a reciprocal fashion.
