An Expanded Mechanism for Rhodanese Catalysis

Journal of Biological Chemistry, 1974
Abstract The kinetic behavior of rhodanese (thiosulfate:cyanide sulfurtransferase, EC 2.8.1.1) was investigated at pH values from 5.0 to 10.8. The binding of thiosulfate was shown to be dependent upon a pK' of 9.9, with the protonated enzyme binding the substrate much more strongly than the deprotonated form. An enzymic nucleophile displaces sulfite to

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2541-2558, April 2026.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Multi‐proteomic profiling indicates potential regulatory signatures underlying rice resistance to Magnaporthe oryzae

The Plant Journal, Volume 126, Issue 2, April 2026.
SUMMARY Omics‐driven approaches can capture systemic plant responses to pathogens. While transcriptomics is a mainstay, it alone cannot capture post‐translational modifications or protein abundance. Because of this, we employed multi‐proteomics to compare the proteome, phosphoproteome, and acetylome of two rice genotypes differing in resistance to ...

Bovine mitochondrial rhodanese is a phosphoprotein

Journal of Biological Chemistry, 1989
The mitochondrial sulfurtransferase, rhodanese, has been analyzed for phosphate content. Significant amounts of protein-bound phosphate (30-40%) were measured in the six rhodanese preparations examined. Chromatographic experiments followed by phosphate analyses done on two of the preparations indicated that rhodanese A and rhodanese B, two enzyme forms

Experts' Opinion on Decontamination and Antidote Strategies: Complementing Contemporary Expert Consensus and Evidence to Optimize Preparedness and Response to CBRN Threats in the Middle East and North Africa

Journal of Contingencies and Crisis Management, Volume 34, Issue 1, March 2026.
ABSTRACT Chemical, biological, radiological, and nuclear (CBRN) incidents present escalating challenges, particularly in geopolitically unstable regions such as the Middle East and North Africa. Despite advances, gaps exist regarding optimal decontamination protocols and agent‐specific antidote selection algorithms, exacerbated by variable operational ...

Supersulfide biology and translational medicine for disease control

British Journal of Pharmacology, Volume 183, Issue 1, Page 115-130, January 2026.
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

Sorghum Poisoning in Livestock: Mechanisms, Risks, and Sustainable Mitigation Strategies

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Sorghum (Sorghum bicolor L. Moench) is a drought‐tolerant crop grown in both arid and semiarid regions and serves as both food and fodder. Under environmental stresses, sorghum accumulates cyanogenic glucosides, especially dhurrin. Through ingestion, dhurrin is hydrolyzed into a toxic element called hydrogen cyanide (HCN).

SERS‐AI‐LUA‐Driven Salivary Diagnosis of Head and Neck Cancer Using Graphene‐Assisted Plasmonic Nanocorals

Advanced Science, Volume 12, Issue 48, December 29, 2025.
The developed graphene‐assisted plasmonic nanocoral platform enables sensitive, label‐free surface‐enhanced Raman scattering analysis of salivary metabolites for head and neck cancer (HNC) detection. When combined with machine learning classification and nonnegative least squares‐based spectral deconvolution, this approach achieves 98% diagnostic ...
