Unraveling the metabolic potential and roles of reductases in the omicsynin biosynthetic gene cluster [PDF]

open access: yesNatural Products and Bioprospecting
Omicsynins are a group of pseudo-tetrapeptides produced by Streptomyces sp. 1647, which exhibited potent anti-influenza A virus and anti-coronavirus activities. However, its biosynthesis mechanism of C-terminus reduction remains unknown. In this work, we

Metabolic Detoxification of Glucose and 4-Hydroxynonenal in Human Neuroblastoma Cell Models [PDF]

open access: yesAntioxidants
Background: Neuroblastoma (NB) progression is influenced by metabolic and redox adaptations. The polyol pathway, driven by aldose reductase (AKR1B1) and sorbitol dehydrogenase (SORD), is activated in hyperglycemic conditions, while detoxification of ...

Aldose and aldehyde reductase exhibit isocorticosteroid reductase activity. [PDF]

open access: yesEuropean Journal of Biochemistry, 1983
In this paper we describe the reduction of corticosteroid metabolites containing the 17 beta-aldol side chain (isocorticosteroids) by aldose and aldehyde reductase from human tissues. Aldose reductase catalyzed the reduction of the aldehydes derived from cortisol and corticosterone at about the same rate, whereas aldehyde reductase preferentially acted

Are glutathionylated aldehyde reductases the missing piece of the “catecholaldehyde hypothesis” in Parkinson's disease? A medical hypothesis concerning the detoxification of 4-hydroxynonenal (HNE) and 3,4-dihydroxyphenylacetaldehyde (DOPAL) [PDF]

open access: yesRedox Biology
The autotoxicity of the monoamine oxidase (MAO) reaction product 3,4-dihydroxyphenylacetaldehyde (DOPAL) is central to the “catecholaldehyde hypothesis”, which posits that interactions between DOPAL and the protein α-synuclein contribute to the ...

Aldehyde Dehydrogenase and Aldo-Keto Reductase Enzymes: Basic Concepts and Emerging Roles in Diabetic Retinopathy

open access: yesAntioxidants, 2023
Diabetic retinopathy (DR) is a complication of diabetes mellitus that can lead to vision loss and blindness. It is driven by various biochemical processes and molecular mechanisms, including lipid peroxidation and disrupted aldehyde metabolism, which ...

Electrochemical Biosensing of Glucose Based on the Enzymatic Reduction of Glucose

open access: yesSensors, 2022
In this work, the enzyme aldehyde reductase, also known as aldose reductase, was synthesized and cloned from a human gene. Spectrophotometric measurements show that in presence of the nicotinamide adenine dinucleotide phosphate cofactor (NADPH), the ...

Activity of the cytosolic enzymes of endogenous aldehydes catabolism under the conditions of different nutrients content in a diet

open access: yesБіологія тварин, 2022
The research was conducted to study the activity of aldehyde dehydrogenase (EC 1.2.1.3) and aldehyde reductase (EC 1.1.1.21), the levels of TBA reactive substances and protein carbonyl derivates in the cytosolic fraction of rat liver under the conditions

Engineered Corynebacterium glutamicum as the Platform for the Production of Aromatic Aldehydes

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Aromatic aldehydes, including 4-hydroxybenzaldehyde (4-HB aldehyde), protocatechuic (PC) aldehyde, and vanillin, are used as important flavors, fragrances, and pharmaceutical precursors and have several biological and therapeutic effects.

Characterization of the novel ene reductase Ppo-Er1 from paenibacillus polymyxa [PDF]

open access: yes, 2020
Ene reductases enable the asymmetric hydrogenation of activated alkenes allowing the manufacture of valuable chiral products. The enzymes complement existing metal- and organocatalytic approaches for the stereoselective reduction of activated C=C double ...
