In enzymology, a 4-hydroxyglutamate transaminase (EC 2.6.1.23) is an enzyme that catalyzes the chemical reaction
- 4-hydroxy-L-glutamate + 2-oxoglutarate [math]\displaystyle{ \rightleftharpoons }[/math] 4-hydroxy-2-oxoglutarate + L-glutamate
Thus, the two substrates of this enzyme are 4-hydroxy-L-glutamate and 2-oxoglutarate, whereas its two products are 4-hydroxy-2-oxoglutarate and L-glutamate.
This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is 4-hydroxy-L-glutamate:2-oxoglutarate aminotransferase. This enzyme is also called 4-hydroxyglutamate aminotransferase. This enzyme participates in arginine and proline metabolism.
