The Role of the [2Fe‐2S] Cluster of Escherichia coli IscR in Responding to Redox‐Cycling Agents
Molecular Microbiology, Volume 124, Issue 5, Page 433-448, November 2025.Redox cycling agents like phenazine methosulfate (PMS) are known for upsetting cellular redox balance. Here we describe how PMS leads to upregulation of the ISC and SUF Fe‐S cluster biogenesis pathways in Escherichia coli when PMS oxidizes the [2Fe‐2S]1+ cluster of the transcription factor IscR, thereby derepressing the operon encoding ISC and, when a ...

The incorporation of labeled lysine into the proteins of guinea pig liver homogenate [PDF]
, 1949 When C14-labeled lysine is incubated with guinea pig liver homogenate, α-aminoadipic, α-ketoadipic, and glutaric acids are formed from the lysine (1). These transformations were established by finding the radioactivity of the C14 tracer in the metabolic ...

Ornithine-catalyzed urea formation in liver homogenate [PDF]
, 1947 Heretofore attempts to obtain synthesis of urea from ammonia (and carbon dioxide) in cell-free extracts have been unsuccessful. We have found the reaction to proceed in guinea pig liver homogenate.

Photosynthetic impact of hypoxia on in hospite zooxanthellae in the scleractinian coral Pocillopora damicornis [PDF]
, 2005 Shallow water coral reefs may experience hypoxia under conditions of calm weather doldrums. Anaerobic responses of endosymbionts (i.e. zooxanthellae) within Pocillopora damicornis coral colonies were tested using both slow and fast chlorophyll a ...

Photosynthetic H2 production: Lessons from the regulation of electron transfer in microalgae
GCB BioenergyGreen hydrogen, produced during microalgal photosynthesis, is regarded as one of the most promising sustainable energy sources. It utilizes sunlight and water, which are essentially unlimited, and its combustion results in only water as a waste product ...
