The Enigma of Sponge-Derived Terpenoid Isothiocyanate–Thiocyanate Pairs: A Biosynthetic Proposal [PDF]

open access: yesMarine Drugs
The co-occurrence of rare terpenoid thiocyanates (R-SCN), structurally similar to their more common isothiocyanate isomers (R-NCS), poses an enigma: how does the accepted path, terpenyl cation R+ → R-NC → R-NCS, accommodate R-SCN?

Improving succinic acid production by tuning polysulfides metabolism in Yarrowia lipolytica [PDF]

open access: yesMicrobial Cell Factories
Backgroud Succinic acid (SA) is a significant C4-dicarboxylic acid with broad applications in the food, chemical, and pharmaceutical industries. In microbial SA production, Yarrowia lipolytica shows great potential. Polysulfides are vital for maintaining

Mycobacterium tuberculosis sulfurtransferase SseA is activated by its neighboring gene product Rv3284. [PDF]

open access: yesFEBS Lett
Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

Rhodaneses Enzyme Addition Could Reduce Cyanide Concentration and Enhance Fiber Digestibility via In Vitro Fermentation Study

open access: yesFermentation, 2021
The use of cyanide-containing feed (HCN) is restricted because it causes prussic acid poisoning in animals. The objective of this study was to see how adding rhodanese enzyme to an HCN-containing diet affected gas dynamics, in vitro ruminal fermentation,

Saccharomyces cerevisiae Rhodanese RDL2 Uses the Arg Residue of the Active-Site Loop for Thiosulfate Decomposition

open access: yesAntioxidants, 2021
Persulfide, polysulfide and thiosulfate are examples of sulfane sulfur containing chemicals that play multiple functions in biological systems. Rhodaneses are widely present in all three kingdoms of life, which catalyze sulfur transfer among these ...

Structural and biochemical characterization of an encapsulin-associated rhodanese from Acinetobacter baumannii. [PDF]

open access: yesProtein Sci
Abstract Rhodanese‐like domains (RLDs) represent a widespread protein family canonically involved in sulfur transfer reactions between diverse donor and acceptor molecules. RLDs mediate these transsulfuration reactions via a transient persulfide intermediate, created by modifying a conserved cysteine residue in their active sites.

Sulfur Administration in Fe–S Cluster Homeostasis

open access: yesAntioxidants, 2021
Mitochondria are the key organelles of Fe–S cluster synthesis. They contain the enzyme cysteine desulfurase, a scaffold protein, iron and electron donors, and specific chaperons all required for the formation of Fe–S clusters.

Transfer RNA Bound to MnmH Protein Is Enriched with Geranylated tRNA--A Possible Intermediate in Its Selenation? [PDF]

open access: yesPLoS ONE, 2016
The wobble nucleoside 5-methylaminomethyl-2-thio-uridine (mnm5s2U) is present in bacterial tRNAs specific for Lys and Glu and 5-carboxymethylaminomethyl-2-thio-uridine (cmnm5s2U) in tRNA specific for Gln.
