Pyruvate dehydrogenase : its structure, function and interactions within the pyruvate dehydrogenase multienzyme complex [PDF]

, 2002
Pyruvate dehydrogenase multi-enzyme complex (PDHC) is member of a family of multienzyme complexes that catalyse the irreversible decarboxylation of various 2-oxoacid substrates to their corresponding acyl-CoA derivatives, NADH and C02.

Nicotinamide Adenine Dinucleotide-dependent Proline Dehydrogenase in Chlorella [PDF]

Plant Physiology, 1974
An NAD-linked dehydrogenase from Chlorella pyrenoidosa Chick catalyzing the conversion of l-proline to Delta(1)-pyrroline-5-carboxylic acid was partially purified. Delta(1)-Pyrroline-5-carboxylic acid was identified as the product by co-chromatography of it and its o-aminobenzaldehyde derivative with authentic compounds. The enzyme is NAD and l-proline

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

Advanced Materials, EarlyView.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

Variability of leaf pubescence characteristics in transgenic tobacco lines with partial proline dehydrogenase gene suppression

Biologia Plantarum, 2022
Proline, an amino acid, plays an important role in plants, and it is involved in stress resistance and development. Earlier, to study the proline role in maintaining stress resistance in plants, we obtained genetically modified transgenic lines of ...

Changes in morphology, proline content, and palatability to Helix aspersa, in Plantago lanceolata in response to transplantation and polluted soil [PDF]

, 1992
High concentrations of heavy metals are a cause of stress in plants, many of which respond by accumulating high levels of the amino acid proline. Tolerant and intolerant plants may vary in their response, and this may be reflected in the palatability of ...

Proline dehydrogenase is a positive regulator of cell death in different kingdoms [PDF]

Plant Signaling & Behavior, 2011
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 ...

Cross Kingdom Metabolic Engineering Paradigm Elevating Sustainable Protein Production

Advanced Science, EarlyView.
ABSTRACT Confronting the dual crisis of escalating global protein demand and unsustainable agriculture necessitates transformative solutions. Here, we pioneer evolutionary insights from maize nitrogen optimization via asparagine synthetase (ASNS) to rewire metabolism in Pichia pastoris.

Proline–Nitrogen Metabolic Coordination Mediates Cold Priming-Induced Freezing Tolerance in Maize

Plants
Cold stress critically restricts maize seedling growth in Northeast China, yet the mechanism by which cold priming (CP) enhances cold tolerance through proline–nitrogen metabolic networks remains unclear.

A bienzyme electrochemical biosensor for the detection of collagen l-hydroxyproline

Sensing and Bio-Sensing Research, 2015
l-hydroxyproline (l-Hyp: trans-4-hydroxy-l-proline) is commonly found at high concentrations in connective tissue proteins such as collagen. It is a remarkably useful molecular marker because variation in the level of l-Hyp is associated with various ...

Integrative Omics Analysis Reveals the Regulation of Hypoxia Tolerance in Large Yellow Croaker (Larimichthys crocea) via the Lipoic Acid Synthase (lias) Gene

Advanced Science, EarlyView.
Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the
