Yeasts, such as Saccharomyces cerevisiae, have long served as useful models for the study
of oxidative stress, an event associated with cell death and severe human pathologies. This …

Protein structure and function can be altered by reactive oxygen species produced either by
cell metabolism or by external oxidants. Although catalases, superoxide dismutases and …

All living organisms require nutrient minerals for growth and have developed mechanisms to
acquire, utilize, and store nutrient minerals effectively. In the aqueous cellular environment …

Zinc is an essential catalytic and structural cofactor for many enzymes and other proteins.
While Zn2+ is not redox active under physiological conditions, it has been known for many …

Reactive oxygen species (ROS) are formed by fungi in the course of metabolic activity. ROS
production increases in fungi due to various stress agents such as starvation, light …

Zinc is an essential cofactor for many proteins. A key mechanism of zinc homeostasis during
deficiency is “zinc sparing” in which specific zinc-binding proteins are repressed to reduce …

Zinc is an essential nutrient and serves as a structural or catalytic cofactor for many proteins.
Thus, cells need mechanisms to maintain zinc homeostasis when available zinc supplies …

Zinc is a ubiquitous metal in all life forms, as it is a structural component of the almost 10% of
eukaryotic proteins, which are called zinc-binding proteins. In zinc-limiting conditions such …

High-temperature ethanol fermentation has several benefits including a reduction in cooling
cost, minimizing risk of bacterial contamination, and enabling simultaneous saccharification …

Zinc-responsive transcription factors are found in all kingdoms of life and include the
transcriptional activators ZntR, SczA, Zap1, bZip19, bZip23, and MTF-1, and transcriptional …
