Chains	Enzyme Name	Description	Catalytic Residues
A, B	glucose-6-phosphate isomerase M-CSA #842	Phosphoglucose isomerase (EC:5.3.1.9) (PGI) [PMID:1593646] is a dimeric enzyme that catalyses the reversible isomerisation of glucose-6-phosphate and fructose-6-phosphate. PGI is involved in different pathways: in most higher organisms it is involved in glycolysis; in mammals it is involved in gluconeogenesis; in plants in carbohydrate biosynthesis; in some bacteria it provides a gateway for fructose into the Entner-Doudouroff pathway. The multifunctional protein, PGI, is also known as neuroleukin (a neurotrophic factor that mediates the differentiation of neurons), autocrine motility factor (a tumour-secreted cytokine that regulates cell motility), differentiation and maturation mediator and myofibril-bound serine proteinase inhibitor, and has different roles inside and outside the cell. In the cytoplasm, it catalyses the second step in glycolysis, while outside the cell it serves as a nerve growth factor and cytokine [PMID:10653639].
