Extracellular superoxide radical (O 2•−) is ubiquitous in microbial environments and has
significant implications for pollutant transformation. Microbial extracellular O 2•− can be …

Enediyne natural products are renowned for their potent cytotoxicities but the biosynthesis of
their defining 1, 5-diyne-3-ene core moiety remains largely enigmatic. Since the discovery of …

In the respiratory chain, NADH oxidation is coupled to ion translocation across the
membrane to build up an electrochemical gradient. In the human pathogen Vibrio cholerae …

Biological nitrogen fixation requires substantial metabolic energy in form of ATP as well as
low-potential electrons that must derive from central metabolism. During aerobic growth, the …

Dehalobacter (Firmicutes) encompass obligate organohalide‐respiring bacteria used for
bioremediation of groundwater contaminated with halogenated organics. Various aspects of …

The study aimed to demonstrate that matrine can reduce apoptosis in H9c2 cells induced by
the cardiotoxic anticancer drug doxorubicin (DOX). The researchers pretreated H9c2 cells …

NADH-ubiquinone (UQ) oxidoreductase (complex I) couples electron transfer from NADH to
UQ with proton translocation in its membrane part. The UQ reduction step is key to triggering …

Pseudomonas aeruginosa is a common cause of urinary tract infections by strains that are
often multidrug resistant, representing a major challenge to the world's health care system …

Vibrio cholerae is the bacteria responsible for cholera, which is a significant threat to many
nations. Curing and treating this infection requires identification of the critical protein and …

Members of the family Prevotellaceae are Gram-negative, obligate anaerobic bacteria found
in animal and human microbiota. In Prevotella bryantii, the Na+-translocating NADH …
