Application


  • Modification of Thiol Enzymes: S-methyl methanethiosulfonate (MMTS) offers a unique method for the modification of thiol enzymes and redox-regulated proteins, providing potential applications in biochemical research focused on enzyme regulation and redox biology (Makarov et al., 2019).

  • Sensor Development for Protease Activity: S-methyl methanethiosulfonate is used as a blocking reagent on the structural transitions of papain-like cysteine proteases, which supports its utility in sensor development, allowing for the detection and analysis of protease activity in various biological processes (Markovic et al., 2023).

  • Agricultural Pathogen Control: Research evaluating S-methyl methanethiosulfonate as a late blight inhibitor highlights its potential as a broad-range toxin against plant pathogens, suggesting applications in agriculture for the management of crop diseases (Joller et al., 2020).
