Microbial Community Dynamics in Marine Water: Influence of Hydrocarbon Type and Exposure Time
Environmental Toxicology, EarlyView.ABSTRACT Marine environments are frequently impacted by petroleum‐derived hydrocarbons, which pose ecological risks because of their toxic, mutagenic, and carcinogenic potential. Microorganisms play a crucial role in hydrocarbon degradation, and understanding the influence of time and hydrocarbon type on microbial dynamics helps improve bioremediation ...

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen
The FEBS Journal, EarlyView.Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

The Electron-Transfer Kinetics of Spinach Ferredoxin with Strong Reductants
, 1982 The reduction of spinach ferredoxin by V(II)-EDTA, Eu(II)-DPTA and propylene viologen was monitored electrochemically. The rates of these reactions were found to be 3.0 · 104, 3.2 · 105 and 1.2 · 105 M−1 · s−1, respectively, by the use of ...

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes
The FEBS Journal, EarlyView.During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

On the role of the acidic cluster Glu 92-94 of spinach ferredoxin I
, 1997 The role of the acidic cluster Glu 92-94 of spinach ferredoxin I in the interaction both with the photosystem I multisubunit complex and the ferredoxin-NADP+ reductase, either membrane-bound or purified, was studied by kinetic characterization of site ...

Thioredoxin system modulates metabolic and stomatal responses to elevated CO2 in Arabidopsis
New Phytologist, EarlyView.Integrative model of extraplastidial NADPH‐dependent thioredoxin reductase/thioredoxin system‐mediated regulation of stomatal function, redox homeostasis, and metabolic responses under ambient and elevated CO2 in Arabidopsis thaliana. Summary The NADPH‐dependent thioredoxin reductase/thioredoxin (NTR/TRX) system plays a central role in maintaining ...
