Some Molecular Properties of Rhodanese
Abstract Fluorescence studies of crystalline bovine liver rhodanese indicate that the reactive sulfhydryl group is in a region which can participate in hydrophobic (apolar) interactions. Fluorescence polarization studies confirm that rhodanese exists in a mobile monomer-dimer equilibrium.

Ergothioneine: Biosynthesis, Molecular Mechanisms, Physiological Function, and Role in Disease
Ergothioneine is a natural thione antioxidant with significant biomedical potential. By reducing oxidative stress, inflammation, mitochondrial dysfunction, and cellular injury, ergothioneine may support interventions for aging‐related disorders, neurodegeneration, metabolic diseases, and skin protection.

Genetic diversity of ‘Candidatus Phytoplasma mali’ strains in Poland
During 2010-2013, samples from 267 apple trees growing in six regions of Poland were tested for phytoplasma presence. ‘Candidatus Phytoplasma mali’ was detected in 17 samples from phloem tissue of apple shoots showing typical apple proliferation symptoms.

Impact of intestinal microbiota on metabolic toxicity and potential detoxification of amygdalin
Amygdalin (Amy) is metabolized into cyanide in vivo, which may lead to fatal poisoning after oral administration. The defense mechanisms against toxic cyanide have not yet been adequately studied.

An Expanded Mechanism for Rhodanese Catalysis
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

AHA1 Regulates Aβ Production via Modulation of APP Abundance and γ‐Secretase Assembly
AHA1 regulates Aβ production through dual mechanisms. AHA1 promotes APP abundance through mechanisms that are at least partially independent of Hsp90 interaction, while cooperating with Hsp90 to regulate APH1/NCT pre‐complex formation, γ‐secretase assembly, and γ‐secretase activity. These coordinated mechanisms contribute to increased Aβ generation and

Characterization of rhodanese synthesized by the wild and EMS-mutated Klebsiella oxytoca JCM1665
Cyanide poisoning remains a significant concern for both civilian and military personnel worldwide. Rhodanese, a cyanide detoxify enzyme produced by the wild (KOJCM1665) and two selected mutant strains (KOJCM1665c and KOJCM1665d) of Klebsiella oxytoca ...

The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications
The Therapeutic Potential of H2S‐Releasing Platforms. ABSTRACT Once known as a toxic gas, hydrogen sulfide (H2S) is now making its way into many therapeutic applications. Similar to its other fellow endogenous gasotransmitters, nitric oxide and carbon monoxide, H2S is a small gas with a short half‐life, making it extremely capable of penetrating ...

Studies on the Active Site of Rhodanese
Abstract The complete loss of enzymic activity on reaction with alkylating agents, aromatic nitro compounds, or aliphatic mercaptans indicates the importance of sulfhydryl groups for catalysis. Analyses during the course of inactivation with any of these reagents revealed the loss of one of the two —SH groups in the rhodanese monomer when inactivation ...
