Application

  • The DmsABC S-oxide reductase is an essential component of a novel, hypochlorite-inducible system of extracellular stress defense in Haemophilus influenzae: This study illustrates the enzymatic action of L-Methionine sulfoxide reductase in bacterial defense systems, underscoring its biotechnological applications in developing antimicrobial strategies (Nasreen et al., 2024).

Actions biochimiques/physiologiques

L-Methionine sulfoxide, a structural analog of glutamate, may be used as a substrate to study the specificity and kinetics of various methionine sulfoxide reductase(s).

3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is widely consumed recreationally. Little is known about its effects on the human metabolome. Mapping biochemical changes after drug exposure can complement traditional approaches by revealing potential biomarkers of organ toxicity or discovering new metabolomic features in
