ALDH4A1

(redirected from delta-1-pyrroline-5-carboxylate dehydrogenase, mitochondrial)

ALDH4A1

A gene on chromosome 1p36 that encodes mitochondrial matrix NAD-dependent dehydrogenase (of the aldehyde dehydrogenase family of proteins), which catalyses the second step of the proline degradation pathway by converting pyrroline-5-carboxylate to glutamate, a necessary step in the pathway interconnecting the urea and tricarboxylic acid cycles.

Molecular pathology
ALDH4A1 mutation causes type-II hyperprolinaemia, which is characterised by accumulation of delta-1-pyrroline-5-carboxylate (P5C) and proline.
