The Role of Hydrogen Sulfide in Evolution and the Evolution of Hydrogen Sulfide in Metabolism and Signaling
Kenneth R. Olson,Karl D. Straub +1 more
TL;DR: The role of H 2S in evolution and the evolution of H2S metabolism and signaling are examined, which shows how much of this biochemical armamentarium easily adapted to an oxic environment where it contributes to metabolism and signaled even in humans.

Metabolism of hydrogen sulfide (H2S) and Production of Reactive Sulfur Species (RSS) by superoxide dismutase.
Kenneth R. Olson,Yan Gao,Faihaan Arif,Kanika Arora,Shivali Patel,Eric R. DeLeon,Thomas R. Sutton,Martin Feelisch,Miriam M. Cortese-Krott,Karl D. Straub +9 more
TL;DR: The studies suggest that H2S metabolism by SOD may have been an ancient mechanism to detoxify sulfide or to regulate RSS and along with catalase may continue to do so in contemporary organisms.

Catalase as a sulfide-sulfur oxido-reductase: An ancient (and modern?) regulator of reactive sulfur species (RSS)
TL;DR: In this article, the authors examined catalase metabolism of H 2 S n, the sulfur analog of the H 2 O 2, hydrogen sulfide (H 2 S) and other sulfur-bearing molecules using amperometric electrodes and fluorophores.

Abnormal mitochondrial oxidative phosphorylation of ischemic myocardium reversed by Ca2+-chelating agents
TL;DR: The results suggest that phosphorylation of ADP by mitochondria from ischemic and isChemic-reperfused myocardium is inhibited by endogeneous ionic Ca 2+ and that this inhibition can be partially reversed by the addition of Ca 2-chelating agents.

TL;DR: In this article, the authors examined reactive sulfur species (RSS) metabolism by Cu/Zn superoxide dismutase (SOD) using amperometric electrodes for dissolved H2S, a polysulfide-specific fluorescent probe (SSP4), and mass spectrometry to identify specific poly sulfides (H 2S2-H2S5).
