Protein Name: Delta-1-pyrroline-5-carboxylate dehydrogenase, mitochondrial

UniprotKB/SwissProt ID: Q8CHT0 (Q8CHT0)

Gene Name: Aldh4a1

Organism: Mus musculus (Mouse)

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 (By similarity)

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Mitochondrion matrix
