Metabolic manipulation by : a powerful stratagem against oxidative and metal stress.

Metabolism is the foundation of all living organisms and is at the core of numerous if not all biological processes. The ability of an organism to modulate its metabolism is a central characteristic needed to proliferate, to be dormant and to survive any assault. is bestowed with a uniquely versatile metabolic framework that enables the microbe to adapt to a wide range of conditions including disparate nutrients and toxins.

Metabolic adaptation and NADPH homeostasis evoked by a sulfur-deficient environment in Pseudomonas fluorescens.

Sulfur is essential for all living organisms due to its ability to mediate a variety of enzymatic reactions, signalling networks, and redox processes. The interplay between sulfhydryl group (SH) and disulfide bond (S-S) is central to the maintenance of intracellular oxidative balance. Although most aerobic organisms succumb to sulfur starvation, the nutritionally versatile soil microbe Pseudomonas fluorescens elaborates an intricate metabolic reprogramming in order to adapt to this challenge.
