Gaseous oxygen is essential to advanced life, but Earth came with no guarantees that oxygen would abound. Researchers are piecing together life9s complex involvement in oxygen9s halting 3-billion-year rise. 
On the Origin of Photosynthesis
The third essay in the Science9s series in honor of the Year of Darwin details researchers' efforts to piece together how and when organisms first began to harness light9s energy. Expand
A chemical systems approach to evolution
A novel approach to the evolution of organisms is given. It asserts that biological evolution was consequential upon geochemical, environment, change and was inevitable not accidental.
Utilization of NGS and Proteomic-Based Approaches to Gain Insights on Cellular Responses to Singlet Oxygen and Improve Energy Yields for Bacterial Stress Adaptation
The ability of photosynthetic organisms to produce O2 dramatically changed the atmosphere of the planet and the life forms sustained due to the accumulation of atmospheric O2 and the evolution ofExpand
Mechanical Stress and Humoral Factors Linked to the Induction of Oxidative Stress
It is demonstrated that pressure overload by aortic constriction increases ROS production in the heart by stimulating the local renin-angiotensin system, and new aspects of the relation between ROS and organ damages are revealed. Expand
Methanogens: a window into ancient sulfur metabolism.
Contrary to this hypothesis, methanogens do not utilize sulfate as a sulfur source, Cys is not utilized as an sulfur donor for Fe-S cluster and Met biosynthesis, and Cys biosynthesis uses an unusual tRNA-dependent pathway. Expand
Enzymatic activation of oxygen in the biosynthesis of polyketide antibiotics
The electron structure of molecular oxygen (O2) is such that it cannot spontaneously react with organic molecules, a feature that protects organisms from oxidative stress. However, oxygenases canExpand

Gasses that can affect oxidative stress and that themselves may be radicals are reviewed, fearing that many of the gasses discussed in this review will induce transient adaptive responses in gene expression that enable cells and tissues to survive. Expand

The main transcriptional regulator to cope with zinc deficiency in Anabaena, Zur, and dozens of genes under Zur control was identified, including putative zinc-binding metallochaperones, other regulatory proteins, and, surprisingly, TonB-dependent outer membrane proteins, which may be involved in active transport of zinc or zinc chelates across the outer membrane.

The Evolution of Type I Reaction Centers: The Response to Oxygenic Photosynthesis
Recent advances in the understanding of homodimeric Type I reaction centers in contemporary anaerobic phototrophs are used to advance a scenario in the evolution of Photosystem I. The transition fromExpand
Sedimentary manganese metallogenesis in response to the evolution of the Earth system
Abstract The concentration of manganese in solution and its precipitation in inorganic systems are primarily redox-controlled, guided by several Earth processes most of which were tectonicallyExpand
