Analyzing Nicotine Action Against Amyloid Toxicity by NMR‐Pharmacometabolomics: An Exploratory Study

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
Combined metabolomic analysis of the intracellular and extracellular portions of SH‐SY5Y cells revealed that, in the presence of Aβ 1–42, nicotine primarily influences pathways related to neurotransmission, energy metabolism, as well as the biosynthesis and degradation of membrane phospholipids.

Evaluation of synthetic formaldehyde and methanol assimilation pathways in Yarrowia lipolytica

Fungal Biology and Biotechnology, 2019
Background Crude glycerol coming from biodiesel production is an attractive carbon source for biological production of chemicals. The major impurity in preparations of crude glycerol is methanol, which is toxic for most microbes. Development of microbes,

SPASM and Twitch Domains in S-Adenosylmethionine (SAM) Radical Enzymes [PDF]

, 2014
S-Adenosylmethionine (SAM, also known as AdoMet) radical enzymes use SAM and a [4Fe-4S] cluster to catalyze a diverse array of reactions. They adopt a partial triose-phosphate isomerase (TIM) barrel fold with N- and C-terminal extensions that tailor the ...

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, Volume 101, Issue 2, Page 751-803, April 2026.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Iron Corrosion via Direct Metal-Microbe Electron Transfer

mBio, 2019
The concept that anaerobic microorganisms can directly accept electrons from Fe(0) has been controversial because direct metal-microbe electron transfer has previously only been indirectly inferred.

Frontiers, Opportunities, and Challenges in Biochemical and Chemical Catalysis of CO_2 Fixation [PDF]

, 2013
Two major energy-related problems confront the world in the next 50 years. First, increased worldwide competition for gradually depleting fossil fuel reserves (derived from past photosynthesis) will lead to higher costs, both monetarily and ...

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 591-605, March/April 2026.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its
