Structural and functional analogue of the active site of polysulfide reductase from Wolinella succinogenes

, 2004
Synthesis of [PPh4]2[Mo(SPh)2(S2C2(CN)2)2] (2) from [PPh4]2[MoO(S2C2(CN)2)2] (1) has been achieved to mimic the postulated {Mo(S)6} core of polysulfide reductase with two thiolates and two bis(ene-dithiolate) ligands.

Molybdenum Cofactor Insertion in Escherichia coli Dimethyl Sulfoxide Reductase

, 2012
Molybdenum is a metal present in all forms of life. Most commonly, it forms the molybdenum cofactor (Moco) in the active site of molybdoenzymes. In bacteria, dimethyl sulfoxide (DMSO) reductase is a molybdoenzyme that is part of the anaerobic respiratory

The Serendipitous Discovery of Rollover Cyclometalation: From Unrecognized Observation to Transformative Chemistry

European Journal of Inorganic Chemistry, EarlyView.
Rollover cyclometalation is a distinctive variant of classical cyclometalation where a chelated heterocyclic ligand undergoes internal rotation, releasing one donor atom from coordination and subsequently activating a remote C─H bond with high regioselectivity.

Biological Effects of Selenium‐Containing Ionic Liquids: Cytotoxicity, Mercury Interaction, and Antiproliferative Activity in Glioblastoma Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Selenium (Se) is an essential micronutrient that participates in redox regulation and cellular homeostasis. Selenium‐containing ionic liquids (ILsSe) have emerged as hybrid compounds combining the properties of organoselenium molecules with the tunable features of ionic liquids.

Determination of Keratinase Activity using Chicken Feather DMSO extract and its optimization with Response Surface Methodology [PDF]

E3S Web of Conferences
Keratinase is an enzyme capable of degrading keratin, exhibiting two activities: protease activity, which cleaves peptide bonds, and disulfide reductase activity, which reduces disulfide bonds (-S-S-). However, keratinase activity is often measured using
