Metabolite Identification
Common NameL-4-Hydroxyglutamate semialdehyde
DescriptionL-4-Hydroxyglutamate semialdehyde is an intermediate in Arginine and proline metabolism. L-4-Hydroxyglutamate semialdehyde is the 4th to last step in the synthesis of Glyoxylate and is converted from L-erythro-4-Hydroxyglutamate via the enzyme 1-pyrroline-5-carboxylate dehydrogenase (EC 1.5.1.12). It is then converted to L-1-Pyrroline-3-hydroxy-5-carboxylate via enzymtic reaction.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Irreversible conversion of delta-1-pyrroline-5-carboxylate (P5C), derived either from proline or ornithine, to glutamate. This is a necessary step in the pathway interconnecting the urea and tricarboxylic acid cycles. The preferred substrate is glutamic gamma-semialdehyde, other substrates include succinic, glutaric and adipic semialdehydes.
