In vitro reconstitution and characterization of pyruvate dehydrogenase and 2‐oxoglutarate dehydrogenase hybrid complex from Corynebacterium glutamicum

MicrobiologyOpen, 2020
Pyruvate dehydrogenase (PDH) and 2‐oxoglutarate dehydrogenase (ODH) are critical enzymes in central carbon metabolism. In Corynebacterium glutamicum, an unusual hybrid complex consisting of CgE1p (thiamine diphosphate‐dependent pyruvate dehydrogenase ...

Plant Pyruvate Dehydrogenase Complex [PDF]

Plant Physiology, 1977
ATP inactivated plant pyruvate dehydrogenase complex (PDC) from broccoli (Brassica oleracea) mitochondria. ATP inactivation of the complex was time-dependent and proportional to the ATP concentration. Time-dependent incorporation of (32)P from [gamma(32)P]ATP into trichloroacetic acid-precipitable protein corresponded to the inactivation of the PDC. It

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Interactions between PPAR Gamma and the Canonical Wnt/Beta-Catenin Pathway in Type 2 Diabetes and Colon Cancer

PPAR Research, 2017
In both colon cancer and type 2 diabetes, metabolic changes induced by upregulation of the Wnt/beta-catenin signaling and downregulation of peroxisome proliferator-activated receptor gamma (PPAR gamma) may help account for the frequent association of ...

Identification of functional murine mitochondrial formyl peptides and their effects on myeloid‐derived suppressor cell generation

FEBS Open Bio, EarlyView.
We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

Membrane Vesicles from Lacticaseibacillus Casei BL23 Exhibit Antimicrobial Activity Against Escherichia coli and Immunostimulatory Effects on Human Peripheral Blood Mononuclear Cells

Advanced Healthcare Materials, EarlyView.
Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

alpha-Ketoglutarate dehydrogenase complex of Escherichia coli. A hybrid complex containing pyruvate dehydrogenase subunits from pyruvate dehydrogenase complex.

Journal of Biological Chemistry, 1985
The alpha-ketoglutarate dehydrogenase complex of Escherichia coli utilizes pyruvate as a poor substrate, with an activity of 0.082 units/mg of protein compared with 22 units/mg of protein for alpha-ketoglutarate. Pyruvate fully reduces the FAD in the complex and both alpha-keto[5-14C]glutarate and [2-14C]pyruvate fully [14C] acylate the lipoyl groups ...

Activity oscillations predicted for pyruvate dehydrogenase complexes [PDF]

FEBS Letters, 1994
A kinetic model for the pyruvate dehydrogenase complex is analyzed. The model takes into account intermediate channeling through the lipoyl network attached to the complex core, as well as inter‐related regulatory effects of protein X acetylation and enzyme phosphorylation. The model predicts undamped oscillations of enzyme activity.

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

Advanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Mitochondrial Encephalomyopathy Associated with Pyruvate Dehydrogenase Complex Deficiency: Eight Clinical Cases

Вопросы современной педиатрии, 2021
Background. Defects in pyruvate dehydrogenase complex (PDC), involved in the glycolysis products integration into the cells' energy metabolism, are one of the reasons of mitochondrial pathology development.
