Abstract De novo purine biosynthesis is required for the incorporation of fixed nitrogen in ureide exporting nodules, as formed on soybean [Glycine max (L.) Merr.] roots. However, in many cases, the enzymes involved in this pathway have been deduced strictly from genome annotations with little direct genetic evidence, such as mutant studies, to confirm

Murburn Concept: A Molecular Explanation for Hormetic and Idiosyncratic Dose Responses
Recently, electron transfers and catalyses in a bevy of redox reactions mediated by hemeproteins were explained by murburn concept. The term “murburn” is abstracted from “ mur ed burn ing ” or “ m ild u n r estricted burn ing ” and connotes a novel “ m ...

Factors Controlling the Reactivity of Hydrogen Sulfide with Hemeproteins [PDF]
Hemoglobin I (HbI) from the clam Lucina pectinata is an intriguing hemeprotein that binds and transports H(2)S to sulfide-oxidizing chemoautotrophic bacteria to maintain a symbiotic relationship and to protect the mollusk from H(2)S toxicity. Single point mutations at E7, B10, and E11 were introduced into the HbI heme pocket to define the reactivity of

Hydrogen sulfide activation in hemeproteins: The sulfheme scenario [PDF]
Traditionally known as a toxic gas, hydrogen sulfide (H2S) is now recognized as an important biological molecule involved in numerous physiological functions. Like nitric oxide (NO) and carbon monoxide (CO), H2S is produced endogenously in tissues and cells and can modulate biological processes by acting on target proteins.

The initial studies of the metabolism of arachidonic acid (AA) by the cytochrome P450 (P450) hemeproteins sought to: a) elucidate the roles for these enzymes in the metabolism of endogenous pools of the FA, b) identify the P450 isoforms involved in AA ...

On‐Demand Chemically Degradable Hydrogels for Biological Applications
This review explores the mechanisms and kinetics of chemically induced on‐demand degradation in hydrogels designed for painless dressing removal and traceless dissolution across various biological applications. Covalent bond cleavage and noncovalent disruption triggers are compared, highlighting opportunities for load‐bearing scaffolds with faster ...
