Repression and catabolite repression of the lactose operon of Staphylococcus aureus
Journal of Bacteriology, 1990 The lacR gene encodes the repressor of the lactose operon of S. aureus. The nucleotide sequence of this gene and the promoter-operator region of the operon are reported. The lacR gene encodes a protein with a molecular weight of 28,534. This protein was found to share sequence homology with the DeoR protein, the repressor of the E.

Frontiers in Microbiology, 2018 Fructooligosaccharides (FOSs) metabolism in Lactobacillus plantarum is controlled by two gene clusters, and the global regulator catabolite control protein A (CcpA) may be involved in the regulation. To understand the mechanism, this study focused on the

Evolving strategies for single-celled organisms in multi-nutrient environments [PDF]
, 2015 When micro-organisms are in environments with multiple nutrients, they often preferentially utilise one first. A second is only utilised once the first is exhausted. Such a two-phase growth pattern is known as diauxic growth.

Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity
Advanced Science, EarlyView.This article describes a regulatory circuit in Escherichia coli able to detect protein–protein interactions with exquisite sensitivity. The interaction between two hybrid proteins fused to Bordetella pertussis adenylate cyclase and its activator calmodulin triggers a potent cyclic AMP signaling cascade.

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.

Proteostasis of organelles in aging and disease
The FEBS Journal, EarlyView.Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Different levels of catabolite repression optimize growth in stable and variable environments.
PLoS Biology, 2014 Organisms respond to environmental changes by adapting the expression of key genes. However, such transcriptional reprogramming requires time and energy, and may also leave the organism ill-adapted when the original environment returns.

In Salmonella Typhimurium, YiiD Modulates cAMP Levels in Lag Phase During Growth on Succinate
Molecular Microbiology, EarlyView.The YiiD enzyme, found by others to perform a redundant role in fatty acid biosynthesis, is found to be unexpectedly required for the early increase in cAMP in lag phase during growth on succinate. This intriguing finding suggests a mechanistic link may exist between fatty acid biosynthesis and catabolite repression. ABSTRACT In Salmonella Typhimurium (
