Non-redundant functions of two proline dehydrogenase isoforms in Arabidopsis [PDF]

BMC Plant Biology, 2010
Background Proline (Pro) accumulation is a widespread response of prokaryotic and eukaryotic cells subjected to osmotic stress or dehydration. When the cells are released from stress, Pro is degraded to glutamate by Pro-dehydrogenase (ProDH) and ...

Functional Impact of the N-terminal Arm of Proline Dehydrogenase from Thermus thermophilus [PDF]

Molecules, 2018
Proline dehydrogenase (ProDH) is a ubiquitous flavoenzyme that catalyzes the oxidation of proline to Δ1-pyrroline-5-carboxylate. Thermus thermophilus ProDH (TtProDH) contains in addition to its flavin-binding domain an N-terminal arm, consisting of ...

Measurement of δ¹-Pyrroline-5-Carboxylic Acid in Plant Extracts for Physiological and Biochemical Studies [PDF]

Metabolites
Background/Objectives: δ1-Pyrroline-5-carboxylic acid (P5C) is a key intermediate in both the pathways leading in plants to proline synthesis, as well as in the proline catabolic route that takes place in the mitochondrion.

Proline dehydrogenase regulates redox state and respiratory metabolism in Trypanosoma cruzi. [PDF]

PLoS ONE, 2013
Over the past three decades, L-proline has become recognized as an important metabolite for trypanosomatids. It is involved in a number of key processes, including energy metabolism, resistance to oxidative and nutritional stress and osmoregulation.

Screening and characterization of proline dehydrogenase flavoenzyme producing Pseudomonas entomophila

Iranian Journal of Microbiology, 2011
Background and Objectives: Proline dehydrogenase (ProDH; 1.5.99.8) plays an important role in specific determination of plasma proline level in biosensor and diagnostic kits.

Exogenous Proline Alleviated Low Temperature Stress in Maize Embryos by Optimizing Seed Germination, Inner Proline Metabolism, Respiratory Metabolism and a Hormone Regulation Mechanism

Agriculture, 2022
Proline (Pro) is not only an important osmotic adjustment substance, but it also plays an important role in regulating plant abiotic stress resistance. The maize varieties, Xinxin 2 (low temperature insensitive) and Damin 3307 (low temperature sensitive),

Intriguing Role of Proline in Redox Potential Conferring High Temperature Stress Tolerance

Frontiers in Plant Science, 2022
Proline is a proteinogenic amino acid synthesized from glutamate and ornithine. Pyrroline-5-carboxylate synthetase and pyrroline-5-carboxylate reductase are the two key enzymes involved in proline synthesis from glutamate.

Proline Dehydrogenase Contributes to Pathogen Defense in Arabidopsis       [PDF]

Plant Physiology, 2011
Abstract l-Proline (Pro) catabolism is activated in plants recovering from abiotic stresses associated with water deprivation. In this catabolic pathway, Pro is converted to glutamate by two reactions catalyzed by proline dehydrogenase (ProDH) and Ɗ1-pyrroline-5-carboxylate dehydrogenase (P5CDH), with Ɗ1-pyrroline-5-carboxylate (P5C) as ...

Altered Levels of Proline Dehydrogenase Cause Hypersensitivity to Proline and Its Analogs in Arabidopsis [PDF]

Plant Physiology, 2002
Abstract Pro dehydrogenase (PDH) catalyzes the first and rate-limiting step in the Pro catabolic pathway. In Arabidopsis, this enzyme is encoded byAt-PDH. To investigate the role of Pro catabolism in plants, we generated transgenic Arabidopsis plants with altered levels of PDH by sense (PDH-S plants) and antisense (PDH-AS plants ...

Biochemical characterization of proline dehydrogenase in Arabidopsis mitochondria [PDF]

The FEBS Journal, 2014
Proline has multiple functions in plants. Besides being a building block for protein biosynthesis proline plays a central role in the plant stress response and in further cellular processes. Here, we report an analysis on the integration of proline dehydrogenase (ProDH) into mitochondrial metabolism in Arabidopsis thaliana.
