Metabolite Identification
Common Name2-Phospho-D-glyceric acid
Description2-Phospho-D-glycerate or 2PG is an intermediate in gluconeogenesis. It is a glyceric acid which serves as the substrate in the ninth step of glycolysis. 2PG is converted by enolase into phosphoenolpyruvate (PEP), the penultimate step in the conversion of glucose to pyruvate. More specifically, 2PG can be generated from Glycerate-3-phosphate via phosphoglycerate mutase or from phosphoenolpyrvate via alpha enolase.

General function:
Involved in magnesium ion binding
Specific function:
Multifunctional enzyme that, as well as its role in glycolysis, plays a part in various processes such as growth control, hypoxia tolerance and allergic responses. May also function in the intravascular and pericellular fibrinolytic system due to its ability to serve as a receptor and activator of plasminogen on the cell surface of several cell-types such as leukocytes and neurons. Stimulates immunoglobulin production. MBP1 binds to the myc promoter and acts as a transcriptional repressor. May be a tumor suppressor.

General function:
Involved in acid phosphatase activity
Specific function:
Acts as a phosphoinositide 5- and phosphoinositide 6-phosphatase and regulates cellular levels of inositol pentakisphosphate (InsP5) and inositol hexakisphosphate (InsP6). Also acts as a 2,3-bisphosphoglycerate 3-phosphatase, by mediating the dephosphorylation of 2,3-bisphosphoglycerate (2,3-BPG) to produce phospho-D-glycerate without formation of 3-phosphoglycerate. May play a role in bone development (endochondral ossification).
