In enzymology, a 2-hydroxy-3-oxoadipate synthase (EC 2.2.1.5) is an enzyme that catalyzes the following chemical reaction:
- 2-oxoglutarate + glyoxylate [math]\displaystyle{ \rightleftharpoons }[/math] 2-hydroxy-3-oxoadipate + CO2
The two substrates of this enzyme are 2-oxoglutarate and glyoxylate, whereas its two products are 2-hydroxy-3-oxoadipate and CO2.
This enzyme belongs to the family of transferases, specifically those transferring aldehyde or ketonic groups (transaldolases and transketolases, respectively). Other names in common use include 2-hydroxy-3-oxoadipate glyoxylate-lyase (carboxylating), alpha-ketoglutaric-glyoxylic carboligase, and oxoglutarate: glyoxylate carboligase. This enzyme participates in glyoxylate and dicarboxylate metabolism. It employs one cofactor, thiamin diphosphate.
