Thiolate Anion - an overview | ScienceDirect Topics
The formation of S-nitrosylation can be favored in with more ionizable cysteine (free sulfhydryl state), such as those in which the thiolate anion can be stabilized by acid–base interactions with neighboring groups, either belonging to adjacent residues in the primary consensus sequence called the nitrosylating motif (Stamler et al., 1997) or ...
Kinetic Characterization of Thiolate Anion Formation and …
2004年6月17日 · Analysis of glutathione (GSH) thiolate formation, which occurs upon mixing activated MGST1 with GSH, reveals biphasic kinetics, where the rapid phase dominated at higher GSH concentrations. The kinetic behavior suggests a two-step mechanism consisting of a rapid GSH-binding step (KDGSH ≈ 10 mM), followed by slower formation of thiolate (k2 ...
Role of Metals and Thiolate Ligands in the Structures and …
2020年8月10日 · Syntheses, structures, and electronic properties of group 5 metal–thiolate complexes that exhibit unusual coordination modes of thiolate ligands have been established. Room-temperature reaction of [Cp*VCl 2] 3 (Cp* = η 5 -C 5 Me 5) with Na 5 [B (SCH 2 S) 4] led to the formation of [Cp*VO { (SCH 2) 2 S}] (1).
Luminescence Onset and Mechanism of the Formation of Gold(I)–Thiolate …
2020年5月11日 · The onset of the luminescence, correlated with the Au(I)–thiolate formation, as well as the kinetics of the luminophore formation were evaluated in terms of the Au(III)-to-alkanethiol ratios. The onset of the luminescence was affected significantly by the solvent polarity during reaction but not post reaction.
