A rheostat mechanism governs the bifurcation of carbon flux in mycobacteria

Nature Communications, 2016
Microbes survive in dynamic environments by modulating their intracellular metabolism. Here, the authors reveal that mycobacteria employ a rheostat-like mechanism to regulate carbon flux between the oxidative TCA cycle and the glyoxylate shunt during ...

The compositional and evolutionary logic of metabolism

, 2012
Metabolism displays striking and robust regularities in the forms of modularity and hierarchy, whose composition may be compactly described. This renders metabolic architecture comprehensible as a system, and suggests the order in which layers of that ...

Lifespan extension in Caenorhabditis elegans insulin/IGF-1 signalling mutants is supported by non-vertebrate physiological traits [PDF]

, 2017
The insulin/IGF-1 signalling (IIS) pathway connects nutrient levels to metabolism, growth and lifespan in eukaryotes ranging from yeasts to humans, including nematodes such as the genetic model organism Caenorhabditis elegans. The link between ageing and

Remnants of an ancient metabolism without phosphate [PDF]

, 2017
Phosphate is essential for all living systems, serving as a building block of genetic and metabolic machinery. However, it is unclear how phosphate could have assumed these central roles on primordial Earth, given its poor geochemical accessibility.

An engineered pathway for glyoxylate metabolism in tobacco plants aimed to avoid the release of ammonia in photorespiration

BMC Biotechnology, 2011
Background The photorespiratory nitrogen cycle in C3 plants involves an extensive diversion of carbon and nitrogen away from the direct pathways of assimilation.

Improved Network Performance via Antagonism: From Synthetic Rescues to Multi-drug Combinations [PDF]

, 2010
Recent research shows that a faulty or sub-optimally operating metabolic network can often be rescued by the targeted removal of enzyme-coding genes--the exact opposite of what traditional gene therapy would suggest.

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, EarlyView.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Genomic variations associated with attenuation in Mycobacterium avium subsp paratuberculosis vaccine strains [PDF]

, 2013
BACKGROUND: Mycobacterium avium subspecies paratuberculosis (MAP) whole cell vaccines have been widely used tools in the control of Johne's disease in animals despite being unable to provide complete protection. Current vaccine strains derive from stocks

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

Animal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

Malate synthase contributes to the survival of Salmonella Typhimurium against nutrient and oxidative stress conditions

Scientific Reports, 2022
To survive and replicate in the host, S. Typhimurium have evolved several metabolic pathways. The glyoxylate shunt is one such pathway that can utilize acetate for the synthesis of glucose and other biomolecules. This pathway is a bypass of the TCA cycle
