Phosphopentomutase

In <a href="/facts/Enzymology/DSI1Fh7y">enzymology</a>, a phosphopentomutase (<a href="/facts/Enzyme_Commission_number/Y5GNLRKX">EC</a> <a href="https://www.enzyme-database.org/query.php?ec=5.4.2.7">5.4.2.7</a>) is an <a href="/facts/Enzyme/DSI1Fh7y">enzyme</a> that <a href="/facts/Catalysis/LPBS7TQC">catalyzes</a> the <a href="/facts/Chemical_reaction/GpqWlKrz">chemical reaction</a>

alpha-D-ribose 1-phosphate 
 
 
 
 ⇌
 
 
 {\displaystyle \rightleftharpoons }
 
 D-ribose 5-phosphate
Hence, this enzyme has one <a href="/facts/Substrate_(biochemistry)/6MnaV19h">substrate</a>, alpha-D-ribose 1-phosphate, and one <a href="/facts/Product_(chemistry)/8uCoDUdv">product</a>, <a href="/facts/D-ribose_5-phosphate/gMzSE2e1">D-ribose 5-phosphate</a>.
This enzyme belongs to the family of <a href="/facts/Isomerase/DtUWnvle">isomerases</a>, specifically the phosphotransferases (phosphomutases), which transfer phosphate groups within a molecule. The <a href="/facts/List_of_enzymes/w2RP6EwU">systematic name</a> of this enzyme class is alpha-D-ribose 1,5-phosphomutase. Other names in common use include phosphodeoxyribomutase, deoxyribose phosphomutase, deoxyribomutase, phosphoribomutase, alpha-D-glucose-1,6-bisphosphate:deoxy-D-ribose-1-phosphate, phosphotransferase, and D-ribose 1,5-phosphomutase. This enzyme participates in <a href="/facts/Pentose_phosphate_pathway/NbuG6Ffj">pentose phosphate pathway</a> and <a href="/facts/Purine_metabolism/mbRrRPDf">purine metabolism</a>. It has 3 <a href="/facts/Cofactor_(biochemistry)/AGo0PCUU">cofactors</a>: D-ribose 1,5-bisphosphate, alpha-D-<a href="/facts/Glucose_1%2c6-bisphosphate/09RIFbVs">Glucose 1,6-bisphosphate</a>, and 2-Deoxy-D-ribose 1,5-bisphosphate.
