Bromination of endo-7-norbornene derivatives revisited: failure of a computational NMR method in elucidating the configuration of an organic structure

open access: yesBeilstein Journal of Organic Chemistry, 2023
Previously we reported on the bromination of endo-7-bromonorbornene at different temperatures yielding mixtures of addition products. The structural elucidations of the formed compounds were achieved by NMR spectroscopy. Particularly, the γ-gauche effect

Synthesis and kinetic evaluation of analogs of (E)-4-amino-3-methylbut-2-en-1-yl diphosphate, a potent inhibitor of the IspH metalloenzyme

open access: yesComptes Rendus. Chimie, 2023
Our previous research revealed that (E)-4-amino-3-methylbut-2-en-1-yl diphosphate (AMBPP) is one of the best inhibitors of IspH, a [4Fe–4S]-dependent enzyme involved in the methylerythritol phosphate pathway that is a valuable target for the discovery of

Microbial (E)-4-hydroxy-3-methylbut-2-enyl pyrophosphate reductase (IspH) and its biotechnological potential: A mini review

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
(E)-4-hydroxy-3-methylbut-2-enyl pyrophosphate (HMBPP) reductase (IspH) is a [4Fe-4S] cluster-containing enzyme, involved in isoprenoid biosynthesis as the final enzyme of the methylerythritol phosphate (MEP) pathway found in many bacteria and malaria ...

Isoprenoid biosynthesis via the methylerythritol phosphate pathway: the (E)‐4‐hydroxy‐3‐methylbut‐2‐enyl diphosphate reductase (LytB/IspH) from Escherichia coli is a [4Fe–4S] protein [PDF]

open access: yesFEBS Letters, 2003
The last enzyme (LytB) of the methylerythritol phosphate pathway for isoprenoid biosynthesis catalyzes the reduction of (E)‐4‐hydroxy‐3‐methylbut‐2‐enyl diphosphate into isopentenyl diphosphate and dimethylallyl diphosphate. This enzyme possesses a dioxygen‐sensitive [4Fe–4S] cluster.

Genetic analysis of benzothiophene biodesulfurization pathway of Gordonia terrae strain C-6. [PDF]

open access: yesPLoS ONE, 2013
Sulfur can be removed from benzothiophene (BT) by some bacteria without breaking carbon-carbon bonds. However, a clear mechanism for BT desulfurization and its genetic components have not been reported in literatures so far.

Stereoselective cardiovascular toxicity of difenoconazole stereoisomers in zebrafish larvae (Danio rerio) through thyroid hormone disruption

open access: yesEcotoxicology and Environmental Safety
Difenoconazole (DIF) is a typical chiral triazole fungicide extensively detected in the environment. This study aimed to explore the stereoselective cardiovascular toxicity of DIF and its four stereoisomers (2S,4S-, 2S,4R-, 2 R,4R-, and 2 R,4S-DIF) in ...

Exploring the electron transfer pathway in the oxidation of avermectin by CYP107Z13 in Streptomyces ahygroscopicus ZB01. [PDF]

open access: yesPLoS ONE, 2014
Streptomyces ahygroscopicus ZB01 can effectively oxidize 4″-OH of avermectin to form 4″-oxo-avermectin. CYP107Z13 is responsible for this site-specific oxidation in ZB01.

Mitochondrial Bol1 and Bol3 function as assembly factors for specific iron-sulfur proteins

open access: yeseLife, 2016
Assembly of mitochondrial iron-sulfur (Fe/S) proteins is a key process of cells, and defects cause many rare diseases. In the first phase of this pathway, ten Fe/S cluster (ISC) assembly components synthesize and insert [2Fe-2S] clusters.
