[3-(Trimethylammonium)propyl] Methanethiosulfonate Bromide (CAS 220560-60-1)

[3-(Trimethylammonium)propyl] methanethiosulfonate bromide (MTSEA-Br), also known as trimethylammonium bromide propylmethanethiosulfonate (TMA-Br-PMTS), is an organosulfur compound that finds applications in biochemical as a quaternary ammonium salt with a bromide anion. One of its important uses is in the detection of metal ions. It has the ability to bind to metal ions such as calcium, magnesium, and zinc. When [3-(Trimethylammonium)propyl] methanethiosulfonate bromide binds to these metal ions, it forms a quaternary ammonium salt with the trimethylammonium group. This binding leads to a change in the electrostatic environment of the metal ion, which can subsequently affect its activity. Additionally, [3-(Trimethylammonium)propyl] methanethiosulfonate bromide is employed in the analysis of protein structure. It has been used to study the binding of proteins to other molecules and to investigate the effects of metal ions on protein structure. By modifying specific cysteine residues in proteins, [3-(Trimethylammonium)propyl] methanethiosulfonate bromide can provide insights into the structural characteristics and functional properties of proteins. Furthermore, [3-(Trimethylammonium)propyl] methanethiosulfonate bromide is utilized in the study of enzyme kinetics. It has been employed to analyze the kinetics of enzyme-catalyzed reactions, allowing researchers to investigate the mechanisms and rates of enzymatic reactions.
