  • 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.
  • Tissue specificity

    Highest expression is found in liver followed by skeletal muscle, kidney, heart, brain, placenta, lung and pancreas.
  • Pathway

    Amino-acid degradation; L-proline degradation into L-glutamate; L-glutamate from L-proline: step 2/2.
  • Involvement in disease

    Defects in ALDH4A1 are the cause of hyperprolinemia type 2 (HP-2) [MIM:239510]. HP-2 is characterized by the accumulation of delta-1-pyrroline-5-carboxylate (P5C) and proline. The disorder may be causally related to neurologic manifestations, including seizures and mental retardation.
  • Sequence similarities

    Belongs to the aldehyde dehydrogenase family.
