L-proline + acceptor = (S)-1-pyrroline-5-carboxylate + reduced acceptor
ping-pong mechanism, the transfer of hydride from L-proline to FAD is rate-limiting for the reductive half-reaction, but the overall reaction is limited by reduced flavin reoxidation in the second half-reaction. Solvent and multiple kinetic isotope effects suggest that L-proline oxidation occurs in a stepwise rather than concerted mechanism

metabolism
-
proline dehydrogenase (ProDH) is a ubiquitous flavoenzyme involved in the biosynthesis of L-glutamate
physiological function
-
proline (Pro) dehydrogenase (ProDH) catalyzes the rate limiting step in the oxidation pathway, transferring two electrons from Pro to the noncovalently bound FAD cofactor to subsequently deliver these electrons to a final acceptor. The plant enzyme sustains oxidative phosphorylation and ATP generation using endogenous electron acceptors. ProDH potentiates the oxidative burst and cell death of the plant hypersensitive response. ProDH converts Pro into DELTA1 pyrroline-5-carboxylate (P5C) and can act together with P5C dehydrogenase (P5CDH) to produce Glu, or with P5C reductase (P5CR) to regenerate Pro and thus stimulate the Pro/P5C cycle. ProDH activation has different effects on hypersensitive response. Before the oxidative burst it leads to Pro consumption involving the action of P5CDH. During the oxidative burst, ProDH becomes functionally uncoupled to P5CDH and apparently works with P5C reductase. The absence of P5CDH does not reduce reactive oxygen species, cell death, or pathogen resistance, indicating this enzyme is not accompanying ProDH in the potentiation of these defense responses. In contrast, p5cdh infected mutant plants display increased reactive oxygen species burst and earlier initiation of hypersensitive response cell death. ProDH may sustain hypersensitive response by participating in the Pro/P5C cycle. Evaluation of ProDH action at different hypersensitive response stages, overview

beta subunit is the L-proline dehydrogenase catalytic component and contains FAD, alpha subunit has a classical dinucleotide fold domain with ATP and a Cys-clustered domain. FMN is located at the interface of alpha and beta subunits
crystal structure of PDH1, which is a heterooctameric complex containing three different cofactors: FAD, FMN, and ATP. The structure is determined by x-ray crystallography to a resolution of 2.86 A. The structure of the beta subunit, which is an L-proline dehydrogenase catalytic component containing FAD as a cofactor, is similar to that of monomeric sarcosine oxidase

EXPRESSION
ORGANISM
UNIPROT
LITERATURE
oxidative burst causes a hypersensitive response with induction of proline dehydrogenase (ProDH), the plants do not consume Pro during maximal reactive oxygen species accumulation, and maintain almost basal DELTA1 pyrroline-5-carboxylate levels at all conditions. Mutant plants lacking DELTA1 pyrroline-5-carboxylate dehydrogenase activate ProDH like the wild-type plants. Under cold acclimation, ProDH induction is accompanied by Pro increase. ProDH activation occuring after stress release does not always be accompanied by P5CDH and can have minor effects on the Pro content
