Sulfur is an essential element required for plant growth. It can be found as a thiol group of proteins or non-protein molecules, and as various sulfur-containing small biomolecules, including iron-sulfur (Fe/S) clusters, molybdenum cofactor (Moco), and sulfur-modified nucleotides. Thiol-mediated redox regulation has been well investigated, whereas biosynthesis pathways of the sulfur-containing small biomolecules have not yet been clearly described. In order to understand overall sulfur transfer processes in plant cells, it is important to elucidate the relationships among various sulfur delivery pathways as well as to investigate their interactions. In this review, we summarize the information from recent studies on the biosynthesis pathways of several sulfur-containing small biomolecules and the proteins participating in these processes. In addition, we show characteristic features of gene expression in at the early stage of sulfate depletion from the medium, and we provide insights into sulfur transfer processes in plant cells.

Sulfur-containing small molecules, mainly including cysteine (Cys), homocysteine (Hcy), glutathione (GSH), and hydrogen sulfide (HS), are crucial biomarkers, and their levels in different body locations (living cells, tissues, blood, urine, saliva, ) are inconsistent and constantly changing. Therefore, it is highly meaningful and challenging to synchronously and accurately detect them in complex multi-component samples without mutual interference. In this work, we propose a steric hindrance-regulated probe, NBD-2FDCI, with single excitation dual emissions to achieve self-adaptive detection of four analytes.

Genome mining is a promising avenue for expanding the repertoire of microbial natural products, which are important for drug development. This approach involves predicting genetically encoded small molecules by examining bacterial genomes via accumulated knowledge of microbial biosynthesis. However, it is also important that the microbes produce the predicted molecule in practice.

Fabrication of Vanadium Oxide-encapsulated Hybrid Carbon Nanospheres for Enhanced Tribological Performance.

A new sulfur-containing carbon nanospheres encapsulated with vanadium oxide (V@SCN) is synthesized through a one-pot oxidation polymerization and then carbonization method. The prepared V@SCNs exhibit good dispersibility as a lubricant additive, which is owing to the inherited lipophilic organic functional groups in the sulfur-containing carbon shell derived from the carbonization of polythiophene. The agglomeration and precipitation of metals in the base oil are also avoided through the encapsulation of lipophilic carbon shells.

Three sulfur-containing alkaloids aplospojaveedins A-C (1-3) with a hitherto undescribed carbon skeleton comprising octahy-dronaphthalene, , -unsaturated lactam and glycine-cysteine moieties were isolated from . Their structures were elucidated by 1D and 2D NMR spectroscopy, HR-MS, X-ray diffraction analysis, DFT-NMR and TDDFT-ECD calculations. A plausible biosynthetic pathway and putative targets are described.

Design and Synthesis of Sulfur-Containing Tetradentate Ligands for Ir-Catalyzed Asymmetric Hydrogenation of Ketones.

Developing highly active and enantioselective ligands for the asymmetric hydrogenation of ketones has consistently attracted significant attention from scientists. A series of novel tetradentate sulfur-containing ligands, termed as f-thiophamidol, were successfully designed and synthesized which exhibited excellent performance in the asymmetric hydrogenation of simple ketones (up to 99% yield, 99% ee) and α-substituted β-keto sulfonamides (up to 99% yield, 99% ee, 99:1 dr). The subsequent successful gram-scale experiments with high TON demonstrated the immense potential application value of this system in synthesizing drug molecules.
