应用


  • 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).

S-Methyl methanethiosulfonate (MMTS) is a reagent used to trap the natural thiol-disulfide state of the proteins. The efficiency of trapping mixed disulfides in vivo has been found to be higher for MMTS than for the more commonly used N-ethylmaleimide. MMTS

The plasticity of cancer cell invasion represents substantial hindrance for effective anti-metastatic therapy. To better understand the cancer cells' plasticity, we performed complex transcriptomic and proteomic profiling of HT1080 fibrosarcoma cells undergoing mesenchymal-amoeboid transition (MAT). As amoeboid migratory phenotype can
