Regulation of Brain Pyruvate Dehydrogenase Multienzyme Complex [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1978
SUMMARY:A number of excellent and comprehensive reviews on various aspects of pyruvate dehydrogenase multienzyme complex have been written recently. The purpose of the present review is to summarize briefly the reaction mechanism and the regulation of this enzyme. Emphasis is put on the most recent literature not covered by previous reviews. Particular

Attachment of the RNA degradosome to the bacterial inner cytoplasmic membrane prevents wasteful degradation of rRNA in ribosome assembly intermediates.

PLoS Biology, 2023
RNA processing and degradation shape the transcriptome by generating stable molecules that are necessary for translation (rRNA and tRNA) and by facilitating the turnover of mRNA, which is necessary for the posttranscriptional control of gene expression ...

Electroenzymatic CO2 Fixation

Angewandte Chemie International Edition, EarlyView.
Electroenzymatic CO2 fixation enables energy‐efficient, highly selective synthesis of complex molecules. Unlocking its full potential requires fundamental understanding of electrode‐coupled reductases and carboxylases. This review critically discusses available enzymes, product scope, and key thermodynamic and kinetic considerations, highlighting ...

Structural insights into the basis and evolution of interactions in multi-subunit protein assemblies. tryptophan synthase and titin FNIII-repeats [PDF]

, 2008
Cellular processes benefit from evolutionary shaping when optimized protein-protein interactions result in enhanced functionality. In fact, most cellular proteins are tightly embedded into biological networks that function following a modularity ...

Ruminococcus flavefaciens 007C cellulosomes and cellulase consortium

Acta Agriculturae Slovenica, 2014
Ruminococcus flavefaciens is among the most important cellulolytic bacterial species in rumen and gastrointestinal tract of monogastric herbivorous animals. Its efficiency in degradation of (hemi)cellulosic substrates is associated with the production of

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Natural Peptides with Antimicrobial Activity

CHIMIA, 1998
Antibiosis is a mechanism by which many cell types control potential environmental takeover or pathogenicity by microbes, especially bacteria. It is now clear that a large proportion of the antimicrobial compounds produced by various cells and ...

Determining the Nutritional Potential of Ancient Wheat Species: A Closer Look at Starch and Protein Digestibility, and Phenolic Acid Content

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The recent trend towards healthy food choices and sustainable agriculture has revived interest in underutilized wheat species such as emmer, einkorn, and spelt. Given these developments, the objective of the study was to compare the differences in chemical composition and digestibility characteristics among ...
