Function

Function:
Besides it's role as a glycolytic enzyme, mammalian GPI can function as a tumor-secreted cytokine and an angiogenic factor (AMF) that stimulates endothelial cell motility. GPI is also a neurotrophic factor (Neuroleukin) for spinal and sensory neurons.
Pathway:
Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 2/4.
Catalytic Activity:
D-glucose 6-phosphate = D-fructose 6-phosphate.
Active Site:
ACT_SITE 358 358 Proton donor.; ACT_SITE 389 389; ACT_SITE 519 519
