The CRISPR‐Cas9 knockout DDC SH‐SY5Y in vitro model for AADC deficiency provides insight into the pathogenicity of R347Q and L353P variants: a cross‐sectional structural and functional analysis

The FEBS Journal, EarlyView.
Here, we generated a DDC‐KO cellular model for studying aromatic amino acid decarboxylase (AADC) deficiency. This model was created using CRISPR‐Cas9 in the SH‐SY5Y neuroblastoma cell line and was validated through the absence of the dopamine product and an altered l‐dopa metabolite profile.

Arabidopsis phenotyping reveals the importance of alcohol dehydrogenase and pyruvate decarboxylase for aerobic plant growth

Scientific Reports, 2020
Alcohol dehydrogenase (ADH) and pyruvate decarboxylase (PDC) are key to the establishment of the fermentative metabolism in plants during oxygen shortage.

In Hyphomicrobium denitrificans Two Related Sulfane‐Sulfur Responsive Transcriptional Repressors Regulate Thiosulfate Oxidation and Have a Deep Impact on Nitrate Respiration and Anaerobic Biosyntheses

Molecular Microbiology, EarlyView.
In Hyphomicrobium denitrificans, the use of thiosulfate as a supplemental electron donor is regulated by two homologous sulfane‐sulfur responsive ArsR‐type transcriptional repressors, sHdrR and SoxR, that act cooperatively. Remarkably, the regulation by sHdrR/SoxR extends far beyond sulfur oxidation and deeply affects anaerobic metabolism, particularly

Pyruvate decarboxylase deficiency in a patient with Leigh's encephalomyelopathy.

The Tohoku Journal of Experimental Medicine, 1982
A 23-month-old boy with progressive muscular hypotonia and mental and motor deterioration was described. Four days after the admission he had a respiratory arrest and required the care in a respirator thereafter. Laboratory examinations showed metabolic acidosis and high levels of pyruvate, lactate and alanine in blood and cerebrospinal fluid.

Characterization of the metabolic shift between oxidative and fermentative growth in Saccharomyces cerevisiae by comparative ¹³C flux analysis

Microbial Cell Factories, 2005
Background One of the most fascinating properties of the biotechnologically important organism Saccharomyces cerevisiae is its ability to perform simultaneous respiration and fermentation at high growth rate even under fully aerobic conditions.

Comparative proteomics analysis of root and nodule mitochondria of soybean

Plant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Pyruvate decarboxylase activity of the acetohydroxyacid synthase of Thermotoga maritima

Biochemistry and Biophysics Reports, 2016
Acetohydroxyacid synthase (AHAS) catalyzes the production of acetolactate from pyruvate. The enzyme from the hyperthermophilic bacterium Thermotoga maritima has been purified and characterized (kcat ~100 s-1). It was found that the same enzyme also had the ability to catalyze the production of acetaldehyde and CO2 from pyruvate, an activity of pyruvate

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Zymobacter palmae Pyruvate Decarboxylase is Less Effective Than That of Zymomonas mobilis for Ethanol Production in Metabolically Engineered Synechocystis sp. PCC6803

Microorganisms, 2019
To produce bioethanol from model cyanobacteria such as Synechocystis, a two gene cassette consisting of genes encoding pyruvate decarboxylase (PDC) and alcohol dehydrogenase (ADH) are required to transform pyruvate first to acetaldehyde and then to ...

Multi‐omic data integration and exploiting metabolic models using systems biology approach increase precision in subtyping and early diagnosis of cancer

Quantitative Biology, Volume 13, Issue 4, December 2025.
Abstract Cancer is a complex and heterogeneous disease characterized by various genetic and epigenetic alterations. Early diagnosis, accurate subtyping, and staging are essential for effective, personalized treatment and improved survival rates. Traditional diagnostic methods, such as biopsies, are invasive and carry operational risks that hinder ...
