Proline Metabolism in Response to Climate Extremes in Hairgrass
Hairgrass (Deschampsia caespitosa), a widely distributed grass species considered promising in the ecological restoration of degraded grassland in the Qinghai-Xizang Plateau, is likely to be subjected to frequent drought and waterlogging stress due to ...

Proline dehydrogenase is a positive regulator of cell death in different kingdoms [PDF]
Proline dehydrogenase (ProDH) catalyzes the flavin-dependent oxidation of Pro into Δ1-pyrroline-5-carboxylate (P5C). This is the first of the two enzymatic reactions that convert proline (Pro) into glutamic acid (Glu). The P5C thus produced is non-enzymatically transformed into glutamate semialdehyde (GSA), which acts as a substrate of P5C ...

In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Evaluation of P5CS and ProDH activity in Paulownia tomentosa (Steud.) as an indicator of oxidative changes induced by drought stress [PDF]
The aim of the study was to investigate changes in proline metabolism in seedlings of tree species during drought stress. One month old Paulownia tomentosa seedlings were exposed to moisture conditions at various levels (irrigation at 100, 75, 50 and 25%

Osmoregulation as a key factor in drought hardening-induced drought tolerance in Jatropha curcas
Jatropha curcas L. is a plant with various commercial uses, and drought is an important limiting factor for its distribution and production. In this study, we investigated the role of drought hardening in an increased drought tolerance in J.

Cloning, purification and crystallization ofThermus thermophilusproline dehydrogenase [PDF]
Nature recycles L-proline by converting it to L-glutamate. This four-electron oxidation process is catalyzed by the two enzymes: proline dehydrogenase (PRODH) and Delta1-pyrroline-5-carboxylate dehydrogenase. This note reports the cloning, purification and crystallization of Thermus thermophilus PRODH, which is the prototype of a newly discovered ...

International audienceProline accumulates in many plant species in response to environmental stresses. Upon relief from stress, proline is rapidly oxidized in mitochondria by proline dehydrogenase (ProDH) and then by pyrroline-5-carboxylate dehydrogenase

ABSTRACT The agitation power input substantially impacts the oxygen transfer rate in aerobic fermentation processes. Furthermore, in a carbon‐limited process where the substrate feed rate is controlled by the concentration of dissolved oxygen, the power input will consequently govern the feed rate.
